I had some old seat cushions that I longer wanted . So I decided to recycle the foam.
I needed a new cushion for one of my benches.
So I cut the rounded corners off each pad and hand sewed them together.
Then I wrapped some material I had around the foam.
Then I hand sewed the material around the foam.
Then I cut four pieces of material to make ties.
Hand sewed these as well.
Its not perfect but it was free.
