From my own experience, I have found that fusible isn't forever and it needs to be sewn down if you want it to last. I longarm my own quilts so I have no problem quilting all the pieces into place so they last forever. You could sew them before you sell them...just use a straight stitch with matching thread or using a clear thread like that made by Superior Threads. I know that would increase your time and add a little more expense to you for the thread, but you could also raise the price of your pieces to properly pay you for your time. *Waving at you from Odessa, WA*!!
