Such an easy way to give a gift card that looks elegant.
Cut your paper to 4 1/4 x 11 and score it along the 11 inch side at 3, 5 1/2 and 8.
You will fold the 5 1/2 inch score to a mountain fold and 3 and 8 in a valley fold.
Now flip the entire card over and tape the outside edge of the card so you create a folded element in the center of the card, trim the top of the folded edge to make an opening for the gift card to be placed. Easy Peasy!
