Remember this? Did you ever work out what it was? No?
It's an advent calendar. Each sock is a different day. To be filled with a chocolatey treat, a christmas decoration, or an activity, a small gift or whatever you would like.
I typed up a list of suggested activities. Some that I have used, some I have not. I tried to keep them family friendly. "Have a glass of Bailey's" is probably not appropriate for the under 10 set. But "Have hot chocolate with all the fixings" is.
I ended up not using the little pegs with santa faces because they were not strong enough to hold the socks. I was sad. They were so cute. They are sitting on my dining room table waiting for a project. The socks are all bagged up and on their way to the recipients. I hope they enjoy it next year.
