The one my mom is making right now:$160.00 for the top and backing with not many leftovers,$30.00 for batting and the cost of your thread. This is all top quality Asian fabric from LQS. The size is about a full size one. I have spent up to $400.00 just for a block of the month one ( I think they cost more anyways). If you have scraps you could really save a lot.
