I have done a dumb thing. I have been working on a BOM this year. I missed a couple of months and finished the blocks up today. Problem? About 2 months ago was going to start a new project and decided to check out my 1/4" seam, make sure is was really a 1/4". It wasn't, it was smaller. So I adjusted the needle so that it measured to the right 1/4". Now the two blocks I made came out 1/2" smaller. Instead of 12 1/2" square, they are 12". Not sure how it happened and makes me think I better check the measurement again. Now I think the easiest thing to do is trim all the other blocks down to 12", or buy more fabric and make the 2 blocks over again. Any advice on this dumb thing I've done???
