Rated 4 out of 5 by from Great looking envelopes The #10 envelopes turned out pretty good. It was the first time I designed envelopes for printing that had lots of color. Next Day Flyers' InDesign template helped a lot. We had color from the flap to the top in the back. Some of the envelopes were slightly off as to where the fold hit.
