Ok, this is what you do to make an awesome sig like the ones i make, k?
1. Download some really awesome brushes of DA
2. Set the opacity to 60%, and stroke around with the colour you want until the pictures completely full.
3. Get the image you want, and paste it.
4. Paste the same image onto the sig until its completely covered,(in other words, multiples of that image is all over the place)
5. Change that layer to multiply.
6. Add text.
7. Add sub text(if you want)
And your done! btw, i forgot to give you the sig i made for you a long itme ago, so here it is:
EDIT: Sorry, filecram got hacked, ill upload it a bit later!
