If you hate it, stop working on it, and give the fabric to a thrift store, or throw it out. There's no sense continuing with it. Wait till you have some money saved up & buy top quality quilting fabrics from now on - don't use WalMart fabric for quilts - it isn't worth all your time, and the cost of batting, etc. You can get great deals for top quality stuff from stores online. And don't feel badly - you learned a bunch - so, move onto a new project, one that you delight in.
