One of my local quilt shops sells bags of remnants for only $4/bag. I've also had luck on eBay and Etsy by typing "cotton fabric remnants" into the search slot. You can refine that search by adding "pink", for instance, or "floral". My latest find was from Etsy where I got a 6-yard x 8" length of beautiful Asian fabric for less than $4 + $2.99 shipping.
