I joined a mug rug swap on Ravelry recently and showed you what I sent off. Unfortunately I understand that the US customs are being extremely slow handling overseas packets so mine has still not reached the recipient.
But I have had a mug rug from a (different) person in the swap, and here it is! Isn't it lovely!
The really nice thing about swaps like this is getting something made in a way or in colours one would not have picked oneself. I would never have thought of the dark grey background, but it makes the bright colours pop very effectively! I must remember this trick myself.
