If you are someone who crochets a lot of doilies or motifs such as granny squares, you might already own a doily stretcher. However, these are usually vintage and can be rather pricey. Another inexpensive way to block a motif is by using a Styrofoam board or square. Lay your item down, pin around it and then steam or spray it with clear water. However, I had an afghan involving a number of large granny squares. I thought I needed something that would be quick and easy to use – like a Blocking Board.
