Some of the socks were made from yarns I’d never used before, but some were made from my favourite sock yarns, King Cole Zig-Zag and Drops Fabel. All socks wear out eventually but these were all still fairly new, so that’s why I was so surprised.
I’ll have to figure out if I can mend them, but it looks like they wear out across the whole sole. Maybe I should change my sock pattern instead. I had no idea floors made that much of a difference, but the last time I lived in a house with a tile floor, grandma still did all the sock mending…
