I have been working my day job and haven't been here for a few days. An easy idea for a pillow is to make it a large 9 patch. Take six 6" x 18" strips of different color cotton fabric and roll hem down both long sides. Then weave them to form a ninepatch. (use all the same fabric if desired) Make a flange back and then with right sides together - serge the nine patch to the flange back. This is a quick, fun and easy project.
Tomorrow I will post the graphic. It is late and I can't get it to paste. Try it with paper first and you will see how easy it goes together.
Don't shop - serge!
