Start with a button-up shirt. Use your former pillow cover as a guide for how big you'll need to cut the new pieces. Cut through both layers of the shirt. An Olfa ruler and cutter makes it easy to get things nice and straight, but scissors will do. With wrong sides together, sew your pieces together. Turn, push out corners, iron. Sew around your shape again using a bigger seam allowance this time. Turn and push out your corners again and you have a nice French seam. Stuff with your pillow form.
And there you go, a pillow refreshed with a shirt saved from the Goodwill pile.
No cost + 10 minutes of work = my kind of project!
Bonus! I still have enough fabric from the sleeves for another little project.
Yep, I know it is a little too snug on the pillow form. The shirt I was working with was a tad bit small and I only had this big pillow form, but I'll take done over perfect any day.
