Three homemade Christmas cookies on parchment paper in a baking tray, shaped like a Christmas tree, a bell, and a gingerbread man.

Making your own decorations - or any mycelium-based creation - is surprisingly simple and a wonderful way to see the true power of the humble mushroom in action.

Mycelium, the root-like structure of fungi, naturally binds together whatever substrate it grows through. In this project, you’ll harness that natural process to grow and shape your own hanging ornaments, which can be dried, decorated, and displayed for years to come.

Using everyday household items, we’ve adapted the same principles used to make mushroom-based packaging and sustainable products. With a little care and patience, your ornaments will cure beautifully - and when you’re eventually finished with them, they can go straight into the compost.

You’ll find this full project in our book Project Mushroom, pages 53–54.

Grow your own Seed Pots with mushroom mycelium.

Out with the plastic and in with the mycelium, here we show you how to make your own, home-made, plastic-free and 100% biodegradable seed pots.

Description

Mycelium is the root system of the mushroom and in this project, it forms and binds together a substrate mix that will not only create stunning pots to support your freshly sown seedlings. Will compost and go on to nourish your soil, disintegrating into food for your worms, while nurturing your growing plants.

At Caley Brothers HQ, we like to show you how easy it is to make stunning products from mushroom mycelium. A process used by many mushroom packaging companies.

As part of your Seed Pot Grow Kit, we send out the freshest grain spawn – this will need to be kept refrigerated until you’re ready to make your kit - to give you the best chances of growing this will need to be kept refrigerated and used within 4 weeks.
