Our house is a bombsite so I'll spend a lot of time cleaning, but here are some nicer things we're hoping to fit in at some point:
Christmas tree collage (cut christmas tree shape from green card then stick on sequins, glitter etc to decorate)
snowman collage (cut snowman shape, stick on cotton balls all over and stick on paper shapes for face, buttons and hat)
Decorate some shaped biscuits which the dds made at their friend's house this afternoon, and hang them on the tree
Christmas Kim's Game: using Christmassy things on a tray, eg bauble, playmobil santa, mince pie, piece trimmed off Christmas tree etc
sprinkle 'reindeer food' on the front lawn (dd2 made this at nursery; it's oats mixed with glitter and sequins)
watch Snowman ballet (recorded on Sky plus last year!)
hot chocolate, bubble baths for dds, new PJs, hang stockings.
after the dds are in bed dh and I hope to have grappa with frozen grapes and chocolate, a Jamie Oliver suggestion (if we're not still ill and full of cold...)
