Hi and welcome! To all of the great suggestions above, I would add that you may find fabric at yard sales. Also, if you'd like to do a project with one "special" fabric and the others from second-hand sheets, clothes etc., you can check Walmart or (depending if you have a store in easy driving distance) get signed up for coupons from Joann's. Almost every month Joann's has a coupon for 40%-50% off a single cut of non-sale fabric and many of the quilting fabrics are offered at similar discounts ("Keepsake Calicos" often go on sale for 50% off and many are $6/yd regular price...another basic line of blender fabrics is often offered at $3/yd as well).
