This is what I am doing also. 40+ blocks into making 80 blocks of 8.5 inches.

I wonder why a foundation is used. Is there some advantage to making string blocks on a foundation? I know I am not planning on removing paper from 80+ blocks but just curious. If you use a muslin foundation are you able to press your seams either to the side or open?

sak658 are you pressing your seams open or to the side? I found that when I lined up a couple of my blocks to check seams I had pressed to the side. there was too much bulk as some of my seams in different blocks came together. So once I finish making my string blocks, I will sit (for hours I'm sure) and press all of my seams open.
