I made several fusible applique projects but not a kit. Hand sewability is all according to the type of fusible involved, you will have to give it a try on one to see if it is doable. Some fusibles are very light and should be easy. I have either machine stitched a blanket stitch or just sewn a straight stitch along the edge of the applique about a 1/16 of an inch in. The fusible should be enough stabilizer.
