Hobbycraft is a great site, would also recommend www.docrafts.co.uk (Anitas etc), and www.artsandcraftsdirect.co.uk (good chat room with lots of swaps etc and advice- the docrafts chat room is great sometimes, but can kick off unexpectedly)
This Christmas I am mostly doing... Spirelli Christmas trees, shaker cards using pre-cut shaker boxes from EBay for the kids, and arts and craft holly wreath stamping. MIL has ordered 10 multipacks to sell at work, so will have to get going soon!
