Darning socks with a Speedweve loom
I love this little device. The weave is tight and long-lasting. Colours are fun to play with, and it's a good activity for fidgety hands.
Original "Speed Weve" darner was released in the thrifty 1940s:

Now sold by Alexon Ver, from Ukraine (www.etsy.com/shop/Alexonver)
I didn't want to deal with customs, so ordered from a Canadian shop (TheGreenThimble.ca).
