Just a simple, little throw pillow. I used an aqua colored sweater vest. It's basically just sewing two rectangles right sides together leaving a few inches unsewn to turn it right side out, then fill with Polyfil and sew the hold shut.
I had a piece of trim for the edges, and the sweater adds some texture.
I did cut 2 rectangles of some scrap fabric to baste the sweater rectangles to. Having each sweater pieces sewn to regular fabric helps keep the sweater from stretching out of shape.
Nothing too fancy, but a quick way to make a pillow and upcycle an old sweater.
