Thanks for the bedtime reading!
I agree with stellaspace about knowing how important participation within the etsy community is. What I wish I'd known more about was photography. There are loads of great guides out there but I think it'd be nice if someone could sort of split a guide as regards different types of things sold on etsy. Photographing a necklace is waaaay different to photographing a huge canvas, for example, and it's all well and good knowing the technical side of taking a photograph (point-and-click!) but there's so much more to it, such as the composition, background, and cropping etc. It's been a real learning curve for me. My standards are so much higher than when I started out in my other shop (twobadbananas) - I hate the photographs in there now and NEED to re-do them!
