Mr. Pen- Interlocking Blocking Mats, 12”x12”, 4 Pack, Blocking Mats for Knitting & Crochet Projects with 50 T-Pins, Knitting Blocking Mats and Pins, Crochet Blocking Board for Crocheting, BMFK04M212

Brilliant size for blocking an adult jumper, good quality with pins included

Nice. Interlocks nicely. Came with a "thank you" from seller. Nice touch. Great for small projects. Will recommend and buy from seller again.

Really happy with these blocking mats! Does the job, comes with lots of pins and is a nice sturdy mat. I've blocked a few of my crochet tapestries on them with no issues. Would recommend

Great purchase. Have never used blocking boards before but will do on all my future knitting projects. Also came with pins which was very helpful.

Be careful to remember the envelope contains pins before ramming your fingers in there. Having one an inch up your nail bed is not fun! 4 stars as I do prefer the solid type as you can fit more squares on at once and I did have to double up on the foam squares to get a solid grip.

Loads of pins and good quality, even had a cute handwritten note thanking me for my purchase. Will definitely buy again if my next project is larger :)

I love these and are brilliant for big projects so happy

Does the job well. And good value for money. Needed something larger for bigger crochet work.used now multipul times and no issues.

These Mr. Pen blocking mats are exactly what I needed for my crochet projects. The interlocking design makes it easy to set up in different shapes and sizes, and they hold together firmly while I work. The 12”x12” size is great for both small and large pieces. The included T-pins are a nice bonus—strong and sharp enough to hold my work in place without damaging the fabric. The surface of the mats is durable and grips the yarn well, making blocking smooth and hassle-free. Overall, this is a high-quality, affordable set that has made my projects look so much more polished. Highly recommend for anyone into knitting or crocheting!

Excellent product.

Amazing blocking board! Because I underestimated how big my finished crochet project was, it turned out a bit too small for it, but the interlocking edges allowed me to pin it anyway! The mat holds pins extremely well: I thought it was going to be challenging given how thin it is, but it was not an issue AT ALL. Lovely packaging and lovely store, will buy from them again 1000%

I’m a relatively new crocheter and these blocking mats worked great for my first granny square blanket! They’re reasonably priced and come with enough t-pins to get you started. Zero conplaints!

Great for blocking squares. Nice and thick. Good quality. Good size.
