Hi Taylor,
I'm quite new to etsy as well and had some fun (and frustration) experimenting with different packaging. I sell jewellery, journals and photography in my shop so every item requires a different size.
I decided to buy my items through an etsy seller - there are so many shops here that specialize in packaging. I used
http://www.etsy.com/shop/ThePetitePackageThe owner was very helpful.
I bought glassine bags, and I wrap each item in tissue before putting it into the glassine bag (then stamp it with my shop name logo). If you go to my shop and click on one of the jewellery items, I have an example of what my packaging looks like.
Simple, clean, affordable and supports another Etsian!
Hope this is helpful,
Reena
