Carpet underlay pieces (NE8)

Leftover underlay from my carpet fitting. There’s a few sensible sized pieces and lots of strips, corners, squares, I just hate so much waste. If someone is fitting their own carpets it may save a little on underlay? It’s underneath so not visible and can maybe be patchworked together?? Theres 3 metal door strips also, these have been used, they were in the flat when I moved in. Also a few odd pieces of the wooden grips. I don’t know if any use to anyone, but thought I would give it a go on here before binning it. Collection only
