I just opened my shop a few days ago but before I opened I did a lot of research about the other shops that sold similar items (I had to see what I would be up against!) I found that a lot of the descriptions are very similar so I figured there was no reason to "re-invent the wheel". I didn't use anyone else's descriptions but it gave me a good idea of what to say about the items I was listing. So maybe look at similar shops to brainstorm some ideas. - I hope it doesn't sound like I copied someone elses descriptions! I just gave my descriptions my own twist.
