Allen,
Here's a poor man's way that I take photos...Take your items outside and photograph with NO flash. Inside will work if you're near a window.....it's the flash that's the problem. Also go to www.picmonkey.com and you can adjust all your photos and even resize them. I use this website for my photos. It's great! And it's FREE!
By the way, your items look fine...good luck with Etsy!
