Hey Marline, thanks for joining! Yes I do have some advice on increasing audience.
For starters, you aren't going to get sales right away, in fact, it may be months between sales. It can get kind of depressing, but you have to stick to it. Joining other etsy teams and frequently posting in the advertising threads has helped me get more views. Also, upgrade your store whenever you come up with another idea. Such as a new lay out, or whether or not you want a banner. Things that show that you haven't abandoned your shop. Creating teams also helps increase your audience, but I don't recommend doing that until you have a little more experience. There is no absolute way to get more sales immediately, it takes a ton of patience.
