Resources have been created that can help you manage sale and distribution of your items to local contacts or if you want a more professional commercial platform then Etsy is one option. I encourage you to get producing your wonderful climate items and then share them with us!
Below you can view a cut-down version of the form that I use to manage scarf orders as I have no interest in running a commercial business. You are welcome to make a copy of it to modify and use for you own endeavours.
Canva is an easy online resource to make professional looking marketing resources if you don't want an online presence. You are likely to be able to get the effect you want with just the free version. Here is a template to get your started
Maybe one of our Etsy craftivists can share their experiences of using it in our facebook group.
First increasing temperatures shattered the Arctic and Antarctic ice shelves, but I did not speak up because I was not affected.
Then it caused deadly European heatwaves, but I did not speak up because I was not affected.
Then it exacerbated tropical storms flooding low-lying pacific islands, but I did not speak up because I was not affected.
Then some glaciers disappeared entirely causing water shortages downstream, but I did not speak up because I was not affected.
Then it bleached the coral, but I did not speak up because I was not affected.
Then it melted the permafrost in Siberia, but I did not speak up because I was not affected.
Then it caused extreme flooding along river valleys due to mega-storm events, but I did not speak up because I was not affected.
Then it caused firestorms and summer-long bushfires but I did not speak up because I was not affected.
Then it caused permanent erosion and flooding of low-lying coastal areas worldwide, but I did not speak up because I was not affected.
When climate disaster finally struck my home there was no-one left to speak up and anarchy reigned.
