1 Pix borders suck, they're too thin.
naw not even. You don't wanna have anything really about 2. I think 2 should be absolute max, but 1 is probably the best. You don't want to cover a whole lot of your sig with the border, you just want a small portion so you just have a frame. That's the only real purpose for a border, and a 1pxl border makes a frame well. But i really think you made a horrible border for his sig, white was a bad colour choice. You should've made it a glassy border, that would've looked much nicer :P.
