At that thickness, they are provide your pins with adequate depth to sink into. Yet, they are thin enough to be easy to carry and use.

The next great feature are the grid lines. Let me explain why these matter. Usually, when blocking textiles, you have to use a tape measure to see if your item is aligned properly. But, with the grid lines on this mat, you don’t need a tape measure as you can use the grids to make these measurements. That is great convenience right there.

Having used crochet blocking mats for a long time, I have had experiences that were not so good. For instance, I once had a board that lost its shape and warped within just 3 months of use. Of course, the board was very cheap, but I didn’t expect it to become useless so fast, lol.

If you want to avoid such a scenario, you’ve got to consider your board’s quality meticulously. Tell you what? The Knitter’s Pride Lace Blocking Mats are cheap but their quality holds.

These are made of compressed foam, but even then, they are pliable. What’s more, they retain their shape for ages.

Another important consideration you need to make is the ease of putting in the pins. You don’t want a board that leaves you with sore fingers, do you?

Do you like to kill fabric? Killing fabric is a common technique used to remove flexibility from fabric like acrylic and give it a relatively rigid size/shape.

When looking for a board, the thickness is one factor you shouldn’t miss to consider. Unless you are working with large pieces of art, there is no need to get an overly thick board. Besides, the bigger the thickness, the more the weight.

Blocking Mats for Knitting Buying Guide

Blocking Mats for Knitting

Whether you’re just starting out or you’ve been knitting for a long time, blocking squares can introduce a whole new look to your creations. The process involves reshaping your knits and allowing them to have even edges, uniform corners, and an overall professional look.

You want to make sure you get the best blocking mats possible. Just like if you’re getting into weaving, you want the best looms for beginners to make things easy.

If you’re seeking these benefits, you’ve got to use the best blocking mat for knitting. Finding them is not easy, and lots of people make the wrong pick and end up deciding blocking is not for them.

On the other hand, if you know what features to look out for or what factors to consider, you will find the right product. And, blocking will be a great experience for you.

Here’s what you need to consider:


It is crucial to consider the material for two reasons is ease of use and durability.

You want a material that your pins can easily go into. For that purpose, foam and rubber are preferred. These are soft enough to pierce without a struggle.

These materials are also adequately durable. They can withstand months or years of use and they are also a bit self-healing.

Also, when looking for your mat, check if it is heat-resistant and water-resistant. That will depend on the quality of the foam or rubber used. Water and heat resistance add to the durability.

When a board is not heat resistant, the colors might melt and get transferred to your project, which destroys your creations. Heat resistance prevents this problem.

First of all, consider the length. It is best to get a mat with a square shape and a length that can accommodate small items like crochets. Usually, knitters go for 12 by 12 inch boards as these are large enough for small knits.

Secondly, think about the thickness. A thicker mat is preferable as it protects your work table from getting scratched or marked during blocking.

For instance, the pins will pierce the table if the mat is too thin.

A thickness of about 0.75 inches is ideal as it is sufficient for the pins to sink into. Thicker than that might make the mat too bulky/heavy.

Is It Gridded?

The whole idea of blocking is to make sure the alignment is good.

Alignment includes ensuring the edges and corners are the sizes you want. That is where the grid comes in. A gridded board with even squares of about 1 by 1 inch makes it easy to measure your project and align it properly.

Usually, if there are no grid lines, you have to use a tape measure, which is too much work. To keep things easy, get a mat with vivid grid lines.

What’s in The Set?

To start blocking, you don’t just need the mat. You also need t-pins. Unless these are included in the set, you have to get them separately, which can end up wasting time and money.

That is why most people prefer to get a set that comes with pins.

Another important accessory is the bag. A nice and sturdy bag is great for storage and transportation.

Apart from that, you may also want a set that comes with many mats. That is because sometimes, you may want to block a large project. In that case, a small 12 by 12 mat won’t suffice. But if you have many mats with interlocking edges, you can set up one large piece that will accommodate your big project.

How to Block Your Knitting with Blocking Mats?

Blocking your yarns using a mat is easier than you think. Depending on the type of fabric you’re working on, you can do either wet or steam blocking.

 Before you block, think about the size of your project. If you’re blocking a small piece, one board will probably be enough. On the other hand, if your project is large, you may want to assemble many mats into one huge board.

Below, we’ll dive into the steps of wet and steam blocking separately.

Wet Blocking

Also called wash n block, this is the more common method, and it is especially suitable for natural fibers. A notable benefit is that it maintains your fiber’s softness.

Let’s go through the steps one by one.

Step 1: Preparation  

Prepare some warm water. You want it to be adequately warm for the fibers to relax but not so hot that it damages them.

You can add some gentle washing fluid to aid in the washing.

Step 2: Wash It

Dip the piece in the water and make sure it is completely wet. Don’t do any kneading or rubbing as that can damage the fibers especially if they are natural.

Let the garment stay put in the water for a couple of minutes. This way, the fibers will relax. After that, you can do some gentle kneading, but not too much to avoid felting.

After a little kneading, let the piece say in the water for an hour or so to further relax the fibers.

Note that relaxed fibers are easier to mold into your preferred size and shape with blocking.

Step 3: Rinse It

You will want to rinse the piece unless you used a no-rinse washing liquid.

So, to rinse, use clean water at room temperature. Again, avoid agitating the garment to preserve the fibers.

You can get rid of excess water by pressing the piece a bit. However, avoid twisting or distorting the garment. You can use a dry towel to remove the excess water. Simply place the piece between two layers and press gently.

Step 4: Time to Block

Lay the piece flat on the blocking board.

The amount and distribution of the stretch you will apply depends on the kind of pattern you want to achieve. Common patterns include lace, cable knit, and plain knit.

For instance, if you want a cable knit, the stretch only need to be light. But, if you want a lace pattern, you do some heavier stretching.

Using the t-pins, prick the garment at the edges and sink the pins into the blocking mat to secure the garment. It is ideal to leave a gap of 2 inches between the pins.

You can use your hands to occasionally stretch out the garment as desired.

Step 5: Let It Dry

Let the garment stay put on the blocking mat for some air drying.

Once the piece is sufficiently dry, take out the pins. By now, the yarn should be in the size and shape you pictured.

Steam Blocking

Does wet blocking seem like too much work and you want a simpler way? Go for steam/spray blocking. This is a more straightforward method.

While wet blocking offers more protection for the fibers, steam blocking is easier and faster. For starters, it doesn’t involve lots of washing and rinsing.

But before you start, note that this method is only fit for small pieces. If the piece you’re blocking is large, steaming/spraying may not wet it sufficiently for blocking, and in that case, it’s better to use wet blocking.

Step 1: Put The Garment on The Mat

Simply lay the garment flat on the board.

Step 2: Make It Wet

Put warm water in a spray can, then spray the garment thoroughly. If your garment has stubborn fibers, you can use a steamer to relax them. However, don’t put the steamer too close to the garment to avoid burning it or the board.

Step 3: Pin The Garment And Block It

Use the t-pins to secure the piece’s edges to the blocking mat. Pull and stretch the piece to make it take your preferred shape.

As you pull and stretch, you can spray the garment some more to help the fibers relax further.

Step 4: Allow It to Dry

Let the garment stay pinned to the blocking mat so it can air dry.

Once the piece is totally dry, take out the pins. You’ll see the garment will have your desired size and shape. Also, take your time! I had to learn how to fix epoxy mistakes because I rushed on other crafts.

FAQs- Frequently Asked Questions

Why do you need to block your knits?

Blocking your projects gives them a professional look. It allows you to bring your knits to your desired size and shape and keep them that way even after washing.

Which blocking methods can I use?

There are two main blocking techniques are wet and steam. Wet blocking is better if you want to protect the fibers, and it involves first washing the garment them blocking it. Steam blocking means you use a spray or steamer, and it doesn’t involve washing the garment first. For bigger yarns, wet blocking is preferred while for smaller projects, steam blocking is better.

How long does block knitting take?

The process itself takes less than an hour mostly. It is the drying time after pinning that consumes time. The drying time depends on the weather conditions or what you do to speed up the drying. While steam blocking can take a few hours, wet-blocking can take a day or two. The trick to speed it up is to try and get as much water out before pinning. You can do that by pressing the yarn between two towel layers.

What can I use to block my knits?

T-pins are the best tools for the job. T-pins are steel needles with a T at the top to aid in piercing and removing.

What can I block my knitting on?

Although I recommend using rubber blocks, you can use just about any flat surface.

Can I use a yoga mat for blocking knitting?

Yes, you can use your yoga mat or even your yoga block for knitting! Although this is not ideal, these are acceptable substitutes that will get the job done.

Final Word

Adding a clean and professional touch to your work is a cinch. All you have to do is block the pieces. With the best blocking mats for knitting, transforming your wrinkly yarns into gift-worthy items will be a piece of cake.
