I made this card for my sister in law for her birthday, but while making it, I didn't really measure to make it a common card size that I had envelopes for. So what I did was cut down one of my bigger bitty bags and used the bag as an envelope! With the bulkiness of the card, this actually worked out perfectly! I wrapped the bag in twine and stamped a gumball tag, I was really happy with the results!
