I used to do a couple of BOMs a year, but the price kept rising (along with the cost of all thing quilty) so I just can't afford it anymore. I will still do the occassional kit. Hoffman and Keepsake are favorites, because they are about the cheapest.
Mostly I quilt from my stash which was, at one time, long and deep, but not being replaced. We have kitted all of my sister's stash, which somehow escaped the purge, by not being labled fabric.
20 years ago when people talked about quilting being a luxury hobby, they had no idea how luxurious it was going to become.
