Good morning and Welcome to the QB from SE Michigan! It is great to see you are just jumping in and to your question you should be fine. The shrinkage on most batting in very little and you could quilt a couple inches more apart with most battings. I would love to see pictures of your baby quilt as well as the L-o-n-g ago quilt. Believe me we all have such quilts in our UFO bins. Again Welcome to the QB and continue to join the fun!
