We had these two old wooden armchairs in the cellar in our old house, because we didn’t really have space for them. When we moved we suddenly had plenty of space, but they still sat in the garage because they had no cushions. Finally in the summer I cut up some old foam mattresses that we had replaced, and made these seat cushions.
The fabric is a couple of tablecloths that I bought from Hemtex (a home textiles store) a few years ago. It’s great to have usable chairs in our entrance, and even better that I was able to use both fabric and foam that I already had!
