I made mini socks in all the house colors so I would be ready when I knew my swap partners house color.
My partner was a Gryffindor .
I also sent a two sided owl ornament , mini sweater in her house colors and a snowman ornament. A Christmas tree to put it all under ;^)
I will knit up another sock to replace the one I sent out so I will be ready for the next swap.
I am waiting to receive mine and will post when I do.
