Recycling socks

I have a habit of throwing all my single socks and socks with holes into a basket and keeping them, the former because many of my black socks are the same type and I like to have spares, and the latter because some time ago I acquired the darning mushroom shown on the left. I wanted to try and see if I could use it to repair some of my favourite fancy socks.

Eventually, even with many of the single socks paired off, the basket filled with coloured socks with holes and black socks that either had holes or couldn't be paired off. I looked at it one day and came to the sudden conclusion that although some of my favourite coloured socks had ended up in there, it might still be years before I felt like sitting down and repairing

old socks, especially ones from which, it turned out, there exuded a slight whiff of sweaty feet despite them being supposedly clean. So I decided to use them for something else instead.

I did a web search for upcycling projects using old socks and came across instructions on how to make sock yarn - sarn - which looked interesting. I already knew how to make fabric yarn (I wonder if English-speaking crafters call it "farn" in keeping with sarn and plarn?), but had not considered making it out of socks. But why not?

It also gave me an idea and I sat down to make sarn from the approximately 30 or so socks that I had accumulated. Now I just have to get going with my project: to use my slightly smelly old socks to crochet...
what else:
slippers.

I will report back when they're done.
