We do have a few 'proper' tools that the kids use with their home made play dough. You don't necessarily need to buy things though. Use things around your home. We used these shapes from a tupper ware sorting ball to press patterns into the dough. Have a look around the house for other interesting shapes to use. Sometimes pieces of lego are fun to press shapes into the dough also. Anything plastic is easy care, as it's easy washable.
