We still need more cushions around the place. I made three new ones last week. The fabric is tablecloths that I bought at Hemtex some years ago (it’s the same pattern as I used on the chair cushions, but in two different colourways).
The backs have a zipper closure. I happened to have three brown zips of an appropriate length in my stash, thanks to impulse purchasing a bundle of 120 zips from Ebay once. I knew that was a good idea!
