I'm thinking about a stable now. A lot of the online demos involve carpentry, but I've found a tutorial that uses cardboard cartons, brown paper, paint and glue, and dried moss. Plus a few twigs! Shall have to ask the corner shop for boxes - they're usually happy to offload them.
Found some small glittery stars in Sainsbury's today - one of those will do nicely on the roof.
I have so much assorted yarn left over, I'm mad enough to be wondering whether to make another next year and offer it to either Gdd's primary, where she'll be in reception, or Gds's pre school - both C of E, so I don't suppose they'd turn their noses up.
