A few months ago I purchased a XL ladies jacket in a thrift store for .99 with the plan of taking it apart to make a pillow for the couch.
My daughter decided to do the project for herself and enter it as a 4H project in the county fair. Here is the jacket after she cut open the seams and cut off the hem.
She cut the top section off at the bottom of the armscye and squared what was left of the back
She used one of the sleeves to make piping. She utilized the front opening keeping 2 of the buttons and the pockets.
The project turned out well, she received a blue ribbon and we think this looks much better as a pillow than a jacket.
