I make
gift card holders from envelopes. Fold a card-sized envelope in half (like it's a
card). Open it back up, and cut the flap of the envelope on the fold, just down to the top of the envelope. So now you have an envelope with two flaps, basically. Seal down the left side.
Gift cards fit nicely into the unsealed (right) side. I usually mount my envelope on a piece of cardstock, to make it a little more like a
card and not just a folded envelope.
I've done lots, but have only posted one to my meager little gallery...

Interesting...I just noticed that the twine I used in this one to tie the envelope shut is on top of the layers of the leaf image. Hm. Usually, I put the twine (or ribbon or string or whatever I'm using) UNDER the image on the front.... Yeah. I'm definitely gonna need to post more of these...
