Heres a way to make them on OpeanSea one of the marketplaces for NFTs but there are many resources. Also there are two invitation only sites for artists called foundation and SuperRare that have the best stuff. It super cool but there is an upfront cost because they are made of blockchain ....I’m thinking about starting with polygon because it’s entirely free I believe but there’s more people involved with etherium. It’s all new to me but why not get in before everyone does?
