So, 3 blocks were a waste - howver I did save them and will make a pillow out of them.
So I cut more thinking it was my fault and checked and checked and measured and measured..and cut enough to make ONE block and still...it was off. I did the pressing not ironing thing. I paid attention to the stretching as I know my fab was 50/50 cotton/poly. I cut for 2 more blocks..and they weren't matching. I was off 1/4 in all the way around. So....I then started cutting the squres (i was cutting from fabric, not charms or jelly rolls) just about 1/8 inch bigger. Instead of 3,1/2 inches, I cut them 3,1/2 PLUS about an 1/8th inch.. I just moved my template ever so slightly toward the 1/8th mark....TADA!!! It worked! I finished the blocks nad they all matched! So I don't know why, but that extra little 1/8 (maybe 1/16th) made the biggest difference! I started another quilt and cut the squares like this and sewed them together and they all match perfectly and measure the 4 inches I want them to. So...maybe try to just add a tiny bit and see how it works. Worked for me
