@alchemistsstudio Without postage: Like @helplessduck said, in your town/village, especially for charity auctions.

With postage paid by the recipient: Via social media posts with hashtags like giveaway, freestuff etc (there's a special one for art but I have to search for it).
Or on #KoFi https://ko-fi.com/ you have the choice to give away art for postage only, as # PayWhatYouWant, or for donators.
You just say to which countries you deliver to and how much the postage costs.
