I was at Goodwill looking for fabric. No yardage there but I did notice bed skirts galore for 1.99 (twin)-3.99 (king). The fabric would equal several yards plus the white fabric of the bedskirt can be used too. I will continue to check the bed skirts when I go back.
ReStore always has many sheets to sell (some are new) as well as bed skirts, and some yardage.
If I am planning particular colors for a quilt, I go to Hancock's who is now having a 40% off quilting fabric sale, or to Hobby Lobby who always has their fabric for 30% off.
Welcome aboard and good luck.
