My "something else" for this challenge is an odd pillowcase that I was ready to put in the Goodwill bag. Then I remembered I had seen an idea earlier on Martha Stewart's website for a pillowcase shoulder bag and thought it would be perfect for this challenge.
I started with pillowcase and cut off 1/2 inch on the closed end.
Cut on diagonal and hem all four edges.
Insert one of the halves inside the other and sew where they
Turn inside out and stitch and trim across bottom.
Tie ends and you have a bag!
