I’ve been designing a lot of envelopes recently and have a few suggestions/requests.
First, it would be really helpful if there were customizable envelopes available for all the size cards that Zazzle offers. The two requests I get most frequently are for envelopes for 3.5x5 inch cards (not sure what size that is) and size A9 - for cards designed on 8.5x5.5 inch paper (cardstock) sheets.
Second, would it be possible to get a product view that included the front as well as both back views (open and closed) of the envelope? Often, most of the design is on the inside flap, but if I choose that view, then customers can’t tell whether the design has a pre-printed return address on the back flap, or a pre-printed mail-to address on the front.
I don’t often design envelopes because I have no idea which cards fit which size envelopes. Those cryptic numbers and letters used to define envelope size mean nothing to me.
Are you trying to design the envelope that is shown with the card? If so, those are not available for design. The envelopes referred to can be found among the products on the left side of the screen of the Zazzle Design Tool.
