I've done both.... I've made three tee shirt quilts without fusible interfacing. Those quilts were stitched in the ditch along the sashings. One was hand stitched/tied (did both because I was just recouping from a stroke and use this as part of my therapy) on the tee shirt sections. The others were hand stitched over the tee shirts. The last one I made was done with fusible lightweight pellon. This one was so large that I had it done by a long arm quilter. It was gorgeous. I think the most important thing is to have the sashings cut to a uniform length on the straight grain of the fabric. This helps to keep the blocks squared. And sew with the sashing at the top and the tee shirt under near the feed dogs. A beginner could easily tie a tee shirt quilt.
