Illustrator CS6, open the swatch palette. They are all the patterns set-up in black. You can change the color to whatever.

I dug forever to find something like this, finally got it from a vendor. Comes in handy for those of you who do envelopes.

Thanks loads! I had to do these a few months ago. Finally found a pattern that looked reasonable, and the custy accepted it. The fun part was getting an accurate outline on the envelope once the custy had torn and wrinkled it opening it up.

thanks dcs! 
if you ever need a template Possum, let us know
It might not be exact but maybe you could tweak it.

Believe me when I tell you, I looked high and low for these patterns. It was nice to finally have something I don't have to manipulate to fit a die. I knew a few of you would appreciate this.
