I finally found an advent calendar for Leah which I didn't have to put together from a kit and wasn't over £30.
I actually found it at our local Church Christmas bazaar for £3!
I had to come up with some ideas to fill it with as I didn't really want to give her sweets or chocolates each day.
I looked on Ravelry for some small toy knits which wouldn't be too time consuming and would be loved by Leah.
The first I found was a pattern for an Amigurimi Pocket Bunny which was a bit fiddly, but pretty cute. Leah keep moaning that iIidn't make it a tail!
The second I have made so far is for a holiday mouse by Fuzzy mitten (this can be found via the link to Ravelry or via her blog). This was a really quick knit and knitted up in just a few hours. As it is knitted straight it wasn't as fiddly and as she uses bobbles rather than knitting arms and legs there is much less sewing!
