I have been going to thrift stores recently to find sheets or pillowcases that I could use to sew stuff and I have found some cheap and cool looking items. Pillowcases are usually $.50 each and sheets are aound $2.00 unless you can get those half off. That's always a bonus! When I was younger my mom used to do this and I always thought that she was such a cheapskate for not buying fabric from the fabric store, now I see that she was a genuis. Mom was right after all.
