I love these 'Decorate Your Own' felt kits for the kids, and we have some we bring out year after year. Hobbycraft have two to choose from this time; a Decorate Your Own Felt Christmas Tree and a Decorate Your Own Christmas Wreath kit. Both are priced at only £6 each, so they're a bit of a bargain.
Each of these sets includes a large green felt background, either a Christmas tree or a Christmas wreath, plus lots of felt shapes to decorate them. Kids can then move the pieces and rearrange the felt baubles, bows, candy canes and more as many times as they like.
I have the wreath in my basket this time, as we already have the tree and a gingerbread house version too, and the kids love playing with them.
These are available both online and in stores, though they do tend to sell out pretty quickly each year.
