the quilts for kids kits are meant to have the backing folded over to the front and machine stitched---they do not want hand stitched bindings---the same is true for the ones you make out of your own fabrics---even if you make a separate binding it should be machine stitched on both sides. they send pretty good instructions with their kits- and it is important to follow them. i've made probably 50 quilts for them over the past few years---it is a wonderful program- and the quilts are very cute!
