I've used satin stitch applique and double sided wonderunder on sweatshirts which get washed more than the usual bed quilt. They usually last over 10 years. The fabric wears and rips from snags first. You have to make the stitch wide enough to cover. Some of the heirloom stitches don't ravel. I use the pin stitch to join lace to a sleeve - fold up a single hem, pin stitch, and cut off any excess. Have done this on nightgowns. It's just harder to turn corners with those than zigzag.
