I saw on the GPP site recently a challenge to make paper casts (link to the right). Its great fun with toilet rolls!! You put thin layers of toilet roll onto your rubber stamps etc then load a paintbrush with water and push the paper into the stamps. You need to do about 5 or 6 layers then leave them to dry thoroughly. Dry brush acrylic paint over them and voila! something out of nothing!! I took them along to a craft group I attend and we all had a go at making them.
