TRULY SIMPLE! I got the basic pattern from a post here at SCS called a Buckle Bag, but I didn't use the Buckle part. So here's how I did it -
cardstock 5.5 x 8.5 (same as for a standard card!) (stamped)
Score at 1 inch along both long sides
Score 3.5 inches from top and 3.5 inches from bottom
CUT the smallest score lines (1 inch in from both sides, near the center)
Fold up the little flaps then foldup the sides and use Sticky Strip near the edge of each side.
There's your bag! EASY!
Then I used a strip 10" long (about 1.5" wide) of Holiday Thyme wrapped around.
The Cranberry square is 2 inch and 1.75 for the stamped tag (by 3.5 if you want it to fold like my tag).
Oh - the handle is 1/2 inch wide by 8.5 long. And I put a strip of grosgrain ribbon down the center of that and attached with brads at the sides.
I'm not sure that was totally clear, so feel free to PM me for clarification.
PS - this will fit a couple little 3x3 cards and envelopes. :) LOVE IT!
