The Block of the Month clubs seem so expensive to me. Some of the quilts are quite beautiful. If you figure the total cost of the quilt, and it doesn't bother you, then go for it. You are right, the cost is spread out over a long period of time. Living in the UK will probably add to the shipping costs. What I did is buy fat quarters and add to my stash. When I had enough, I started a scrappy quilt that is very labor intensive. It is about 3/4 done, and I'm in no rush to get it done.
