The walnuts are collected from our organic farm, and hand shelled. Walnut shells can be used to make walnut shell doll cradles - we use them to create our little nutters. You can also have fun adding sails to make boats. Have a look on google images for loads of other creative ideas on what you can do with the shells. This batch of shells come in a variety of conditions, mostly imperfect, as they are a few years old. Starting from March this year, we'll be collecting a fresh batch.
