I ordered Stickers today for Funkwhale. There will be two versions, one times A8 with Logo + name and a round, logo only one. As soon as they are there, I'll post a picture here.
If you want to have a set of stickers, I can send some. You can order them by sending an E-Mail to firstname.lastname@example.org. Please add your Address where I should send the stickers and a number, how many you "need".
I will do all this for free of course! Still, if you can and want, I'd appreciate some donations to the Funkwhale collective. This can be done either by visiting our Open Collective Profile.
