I'm currently doing a quilt a long on Craftsy where I found out two blocks into the class that all seams were to be sewn with a scant 1/4. Amy Butler (who is teaching the class) said something to the effect "I thought everyone sewed with a scant 1/4 inch".........Ok, what planet is she on? My blocks are now just short of the 12 1/2 inch finished size, but I am just going to cut mine down to 12 1/4 inch.....YIKES!!!! Just when you think you have all the answers, they change the questions!!
