Sheets and pillow cases at thrifts centers! I just bought a king size sheet last week for $1.00. Same fabric on bolt at Joanns, $7.99 yrd (on sale). Pillow cases were .25 each. I'm very excited to cut into the sheet it is blue and white plaid and with a fitted sheet as a bonus piece. it doesn't matter where the fabric comes from, as long as you enjoy bringing it to your sewing table. Good luck!
