I don't think I want to know. I do it because I love to create and consider myself a sloooooooow piecer and quilter. I FMQ them all because I now have a Tiara and I am also slow. Love applique which also slows me down. All a labor of love for people I love or those in need. I never sell them, so it doesn't matter to me, though I have been curious about it, but not enough to pursue LOL
