I've got a set of envelope templated I bought from Lakeland ages ago and one of the sizes makes envelopes for 7 by 5 cards. Trouble is Lakeland stopped selling craft stuff a while back.

If I get time I'll have a play and see if I can work out the sizing on Crafters Companion Enveloper or Martha Stewart Scoreboard.

However at the moment I have a small stock of 7 x 5 cards and envelopes that I bought from The Works.
