I love the fact that you can use a bunch of hashtags on a single Instagram post and no one really minds about how spammy it is. Because it's just what's done on Instagram.
And unless you have a huge - and I mean massive - following, you probably won't be seen all that much without them. So the more you use, the better your chances of being found.
The limit for number of hashtags per post is around 30. I tend to split these between the caption and a single comment straight after posting, which seems to work fine. And I'm always on the lookout for the latest most relevant hashtags I can use to promote my handmade items.
Below is the list I currently use including some new ones I plan to use over my next few posts.
