When I decided to learn to quilt I signed up for a class. Like you, I went for the cheapest fabrics available. I bought a bunch of patriotic fabrics at JoAnn's that were on sale since the holiday had passed. I made a bunch of blocks in the class, laid them out and decided that the fabrics were horrible together. So I put those blocks and the remaining fabric aside, bought some fall fabrics at Walmart, and made that first quilt. But I kept the original blocks. Years later, I pulled them out and finished up that patriotic quilt with the horrible fabrics - and I love how it turned out! Here's the quilt -

So, my point is that you may find that your tastes change down the road. Don't give up on your first quilt, but if you're tired of working on it then give yourself permission to start something else.
