I used French fuse at the suggestion of a quilt shop on my t shirt quilt. For my daughters baby clothes quilt I used the lightest stabilizer I could find at Joann's and it worked well. I would definitely use it on any knits, onesies, t shirts etc, if you have fleece pjs or other things you wouldn't need it. I used minky on the back and love it..it's heavy but nice and soft and fluffy.
