I'm on an internet forum where there's a large contingent of members asking for custom sigs. Here's some of my work. The sigs that have a dark gray background are made to match the site's background color, so on hat site, they appear seamless and floating. Before anyone asks, yes I know how to make floating .gifs or .pngs but I try to make them small enough for to use the site's onboard uploader. I used Colin's "Bling" tutorial for one of them!
Thanks for looking.
