A fellow Etsian directed me to this awesome website to use for cleaning up my pictures of my Etsy items prior to listing them for sale. If you need to crop or alter some photos, you MUST check this site out - it's amazing! Better yet, most of its features are FREE! You can upgrade to a premium account for about $25 and get some additional features, but everything I need is free and I love it that way!
Here are a few pictures I've played with today; you'll get an idea pretty quickly for all this site can do!
