If you have a creative kid like my Smix, then crafting kits make great smaller presents or surprise gifts at Christmas.
The Nutty Putty set we received included 5 colours of clay, 4 shape cutters, 2 tools, a rolling pin, a baking sheet and instructions. The instructions are quite clever in that they double as a laminated mat to do your building & sculpting on. As it is the clay is non-staining, so you aren't going to end up googling how to remove clay from your sofa.

We have a kit to giveaway to one of my readers. Competition closes this time next week, so I can hopefully get it to you before Christmas. Good luck!
