Check out the thrift shops. Not only can you find cotton clothing to cut up, but they often have fabric donated. Also, use sheets for backing ( the inexpensive sheets with lower thread counts are actually easier to quilt). I have used flannel (buying a large flannel sheet is pretty cheap) instead of batting in small throws and inexpensive clearance thin blankets (from a discount outlet). I recently made a throw out of men's shirts cut up - very different and kind of fun. Try using these options and use whatever money you have for that 'special' piece as your focal fabric. And, watch the sales and coupons. I sell my throws size quilts but only because I rarely pay more than $4 per yard (and often less) on the fabric. And please keep in mind, the person receiving your gift is going to be thrilled that you spent your time making them the quilt (or placemats or table runner), they are not going to be checking on how much you spent.
