Oooh, I just recently bought a mushroom ...believe it or not actually for darning! Hubby won't throw away his old jumpers and wears them while full of holes if I don't darn them! Now when I've repaired the jumpers I'll have another use for it! 😄
I have one like that Penguin! Won't get rid of his favourite jumpers. I can darn, but refuse to, however I do sew on felt elbow patches, after all we all have bits of waste felt lying around.
