i have never been happy with a machine applied *front & back* binding---mine always just (in my opinion) ruin the quilt- i don't even try anymore- i figure if i'm going to put the work into the quilt it makes no sense to ruin it by taking a short cut at the end- so i machine stitch to the front- fold to the back & hand stitch into place-
i know there are a ton of tutorials out there showing ways to do it- & some people will use a decorative stitch - but the few quilts i have tried them on i have been so horribly disappointed with i would never take a picture of it- the quilts generally wind up just going to goodwill
