i made sure all seams were 1/4 in even pinned every strip used starch this is the third baby quilt i have done and this is the first to do this and it just wasnt the couple spots all but about 4 patches did this i guess i should go back to not being as careful about everything as in the other 2 i did not wash on delicate as i always wash my quilts first as a non quilting person would this is a baby quilt and it is going to need to be put thru rigourous treatment the one thing i will try next time is short smaller stitches
