L.D.
I made designer drapes and a table cloth using remnants from a high end fabric/upholstery store and "wonder under." Fabric cost @ $2/yard. Wonder under is a strip that is made to hem pants without sewing - just fold the fabric up and iron. I used it to make the curtain rod casing at the top, and then hem the bottom. Voila! Toile curtains!
You know those promotional bags you get at events? That have the company's name and logo on it? Get some cute fabric and cut it in an oval or circle to cover the logo. Use heat and bond to iron the fabric on. THEN cut your child's initals out (or a flower shape or car shape or heart) of a different fabric, and heat and bond that on top of the circle. Now you have an almost free custom gym, soccer, or ballet bag for your child!
