You must have had reasons for picking the fabrics and patterns you did. I don't think its unusual to start second-guessing oneself when it comes to gift quilts. I would recommend that you at least finish the top. Think about why you are having second thoughts and try to pinpoint what you're feeling. If you can sort that out a bit, a decision might present itself about either finishing this quilt as intended, or putting the top aside and starting fresh with a new quilt. I don't see any sense in cutting this top apart and using the same fabrics in another pattern for the same purpose. If you decide to start fresh, put this top aside and take it up again at a later time.
