Isn't it cool that you can now make a gatefold card without worrying about measurements? Even better is the unique leaf and floral edges to make it even more special!
Enter - the Gatefold Blossoms Framelits dies! These cards when closed measure 3-1/2" x 5" which is a note card envelop size. You can use the envelops from the "Notecards & Envelops packs" to put them in, or you can use your Envelop Punch Board to make a bespoke one.
It goes without saying that the stamps which co-ordinate with the dies can be used for normal sized cards too and should you desire, you can use them to stamp on your Scrapbooking projects!
Here's the supplies list I used.
