I was looking up blocking boards online for granny squares, and they were all so expensive! I printed a few but wasn't able to find one large enough for the 7 inch squares that I had made, so I made this one! It's the perfect size for the Red Heart granny square yarn.

It's designed for multicolor printers - you can still print it with a single color printer, but you won't have the design embedded. I've included both an X1C 3MF file, as well as one for A1 models.

I made the pegs with 5 walls so they're nice and sturdy, and the profile prints with 8 pegs - 4 long ones and 4 short ones. If you want it to stand up, put several of the long pegs in the front, and it'll lean nicely on them. The other upside is that it's plastic, so you can get your yarn super wet and you don't have to worry about it warping.

I'm still experimenting with how many squares you can block at a time, I've gotten 4 on the short pegs so far.

I made it with a decorative motif in the middle that matches my crochet hook & stitch marker holder. Printed together, they'd make a lovely gift set for your crocheting friends! Thanks for looking! If you print it, let me know - I love to see pictures of what other people make! :)

Some printing notes - like I said, the pegs are 5 walls so they're pretty sturdy. I recommend watching it for the first hour to make sure there's no lifting on the corners. I wound up using gluestick on the corners to make sure they wouldn't lift, and it worked out well.
