Instagram is by far my favourite form of social media. It takes time to build a following (mine is still small) but it's a lot of fun. It's important to post good quality photos and use lots of relevant hashtags (I think the limit is 30 so don't be afraid to use them!) There are lots of accounts that share small businesses too so make sure to find and tag them in your posts and your work might get shared with larger audiences.
Also take the time to engage with other people - like, comment and support other makers that you genuinely like. I've built lots of relationships this way and it helps you to get noticed. Make sure you keep active and don't just wait for people to come to you. Hope that helps some of you!
