Its is very possible to quilt your own quilt on your domestic machine. I've done all of mine that way. Its a little more trouble, but the sense of completeing it totally on your own is worth it to me and I just don't have the room or inclination to buy a LA right now. Here is a link to the one I'm finishing up right now.
