TUT~Security Tangle

For this swap we will be using the inside of a security envelope. Either attach a piece of envelope to entirely cover a sturdy 3.5" square tile and tangle over it, or attach some cut out shapes (or just one) to your tile, and tangle around them. You can use black and white or color, and as many tangles as you choose. Write the usual info on the back (swap name, user name, month and year, and tangles used.

Add some decoration to your envelope.
