I always have plenty of cards on hand for any occasion - but I end up running around the house, trying to find an envelope to go with it. Well, if you are like me, then you are going to love the Envelope Punch Board. This is the coolest tool ever! It a matter of a minute, you can make a custom envelope (In over 60 sizes!). The tool scores and punches - and then you just add your adhesive.
Here's just a quick sampling:
You can make a tiny gift envelope up to a large 6 x 8.5" envelope - all from 12 x 12 cardstock.
And there is no need to keep the envelopes plain - you can decorate them to suit your tastes.
