My very first quilt was an around the world with 3" flannel blocks!!! I did wash it a few times first, and then to deal with the stretching, a slow laborious project before I had a walking foot, was stitch half way down the block, take out, and stitch down the other side, meeting n the middle. What a job, but, the corners matched and the quilt is 7 years old and washed a zillion times and still in every day use.
