I know this may be a silly question but yes, you're dealing with a newbie and
as i'm progressing with photoshop, certain things aren't quite clear. I'm trying to create my own signature but i don't know how to blend images and create like a grid, kinda translucent. well , all i managed to do was just to start with clouds then changed the hue/saturation..and messed with the blending options and added some text but that's about it.
I'll be posting my recent signature
