These are mushroom charms to trade at Artfest.
They are for sale in my etsy shop either in packs of 4 or individually (those will be listed tomorrow). I found the coolest recycled card to print them on. It's made here in the UK and it comes in 4 colours/flecky bits: white with grass (my absolute favourite), white with straw, cream with straw and white with banana peel. All the bits are agricultural waste from farms, animal feed, landscaping, etc. The envelopes match, but have nothing printed on them.
