7 Best Blocking Mats For Blocking Blankets To Use
Blocking blankets requires the right surface. We review the 7 best blocking mats to ensure your knit projects stay flat, secure, and perfectly shaped every time.
Blocking is the single most transformative step in any knitting project, turning a rumpled piece of fabric into a professional-looking garment. When you are working on a large blanket, the right surface is the difference between a relaxing finish and a frustrating battle with gravity. These mats provide the necessary structure to open up your stitches and set your final dimensions. Choosing the right set will save you hours of physical strain and ensure your hard work looks its absolute best.
Knitter’s Pride Lace Blocking Mats: Best Overall
These mats are the industry standard for a reason, striking the perfect balance between density and ease of use. They are thick enough to hold a T-pin securely without it poking through the other side, which is vital for heavy wool blankets.
The interlocking teeth are precision-cut, meaning they don’t gap when you join them together. This creates a seamless, flat surface that won’t snag your delicate lace or snag-prone mohair yarns.
If you are a serious knitter who tackles everything from intricate shawls to massive afghans, these are a reliable investment. They hold their shape over years of use, making them the most cost-effective choice in the long run.
Mindful Collection Patterned Blocking Mats
These mats feature a beautiful, subtle mandala print that serves a very practical purpose beyond aesthetics. The pattern acts as a visual guide, helping you keep your edges straight without needing to pull out a measuring tape every few inches.
The surface texture is slightly grippy, which prevents your knitting from sliding around while you are pinning. This is a game-changer when you are working with slippery fibers like alpaca or silk blends that tend to migrate while wet.
While they are aesthetically pleasing, the real value lies in the consistent, high-quality foam density. They are firm enough to provide good tension, yet soft enough that your fingers won’t ache after an hour of pinning.
Clover Locking Blocking Mats for Precision
Clover is known for its engineering, and these mats are no exception. They feature a unique locking mechanism that ensures the mats stay perfectly aligned, even if you are stretching a heavy, water-logged wool blanket to its maximum dimensions.
The surface is marked with a grid, which is essential for achieving perfect symmetry. If you are blocking a blanket with complex geometric colorwork or cables, this grid acts as a blueprint to ensure your finished piece is square.
These mats are slightly firmer than the average foam board. This makes them ideal for knitters who prefer to use blocking wires rather than individual pins, as the edges remain stable under the pressure of the wire’s tension.
Darice Foam Blocking Mats: Best Budget Pick
If you are just starting your journey or only block a blanket once a year, you don’t necessarily need the most expensive professional equipment. These mats provide a functional, accessible surface that gets the job done without breaking the bank.
They are thinner than premium mats, which means you need to be mindful of your floor surface. If you are working on a hard floor, you might feel the pins hitting the ground, so consider laying down a towel underneath for extra protection.
These are perfect for the occasional project or for knitters who are building their toolkit incrementally. They are lightweight and easy to store, making them a great choice for those with limited space in their craft area.
Exquiss Interlocking Thick Foam Floor Mats
Often marketed as play mats, these thick foam tiles are a secret weapon for knitters with large-scale projects. Their extra thickness is a major advantage when you are dealing with heavy, dense blankets that require significant tension.
Because they are so thick, you can push your T-pins in at an angle to create extra tension without them ever reaching the floor. This is particularly useful when blocking heavy wools that have a lot of "memory" and want to shrink back to their original shape.
The trade-off is that they take up more storage space than purpose-built knitting mats. However, for a dedicated knitter who always has a blanket on the needles, the stability they offer is well worth the footprint.
We R Memory Keepers Grid Surface Blocking Mats
These mats are designed with the crafter in mind, prioritizing the grid layout above all else. The printed lines are high-contrast and easy to see, which is a massive help when your eyes are tired from hours of finishing work.
The material is high-density, preventing the "pitting" that happens on cheaper foam after repeated use. If you are someone who keeps their projects blocked for a long time to allow the yarn to "bloom," this durability is essential.
They are particularly well-suited for blocking items that require exact measurements, such as pieces intended to be sewn together. You can trust that your dimensions will be accurate every single time you set them up.
Tiamat Extra Thick Extra Large Blocking Mats
When you are blocking a queen-sized afghan, the last thing you want to do is constantly move your mats around. These extra-large tiles cover more square footage with fewer seams, creating a more stable foundation for your largest projects.
The thickness is the standout feature here, providing a deep, secure hold for even the longest blocking pins. You won’t have to worry about pins popping out under the weight of a heavy, saturated blanket.
While the size is a benefit, ensure you have a clear space in your home to accommodate the footprint. These are the "heavy artillery" of blocking mats, designed for the knitter who treats their blanket projects as serious, long-term endeavors.
How to Choose the Right Blocking Mat Material
Not all foam is created equal, and the density of your mat will dictate how well it handles different yarn weights. For heavy, worsted-weight wools, you need a high-density mat that won’t compress under the weight of the damp fiber.
- High-Density Foam: Best for heavy blankets and long-term blocking.
- Grid-Printed Surfaces: Best for precision and matching pattern repeats.
- Interlocking Systems: Best for modularity and custom shapes.
Avoid overly soft, "squishy" foam, as it will lose its shape quickly and fail to hold your pins securely. The best mats should feel firm to the touch, similar to a high-quality yoga mat but with a more rigid structure.
Essential Tips for Blocking Large Blankets
Blocking a large blanket is a physical process, so start by ensuring your space is clean and free of debris. Always use a moisture-wicking towel to pull excess water from the blanket before pinning it to the mats to prevent the foam from staying damp for too long.
When pinning, start from the center and work your way out toward the edges. This prevents the blanket from becoming lopsided and ensures an even distribution of tension across the entire piece.
Don’t be afraid to use plenty of pins. For a large blanket, a pin every two or three inches is standard, but you may need more if you are trying to open up a complex lace pattern.
Maintaining Your Blocking Mats for Longevity
After you have finished blocking, always allow your mats to air dry completely before stacking them away. Trapped moisture is the enemy of foam, as it can lead to mold or degradation of the material over time.
Store your mats in a cool, dry place and avoid folding them, as this can create permanent creases in the foam. If you have the space, keeping them flat or standing them up vertically is the best way to maintain their structural integrity.
If your mats become dusty or covered in stray fibers, a quick wipe with a damp cloth is usually sufficient. Avoid harsh chemicals or abrasive scrubbing, which can damage the surface and make it harder to pin your work in the future.
Investing in quality blocking mats transforms the final stage of your project from a chore into a rewarding ritual. Whether you choose the precision of a grid-marked surface or the heavy-duty support of extra-thick foam, your blankets will thank you with a superior drape and professional finish. Take your time, choose the set that matches your space and project volume, and enjoy the satisfaction of seeing your stitches truly come to life. Happy knitting, and may your edges always be straight and your tension perfectly set.
