I tend to design things I need then share. Here is a sheet of Xmas tags for you. Hopefully you will find them useful!
There are a few different styles so hopefully one of them will appeal! If not, I do have a ton of Xmas stuff in the menu under Freebies & Project Life Printables at the top. Lots of tags there – here are a few (links to all, and more, in the menu link):
There are also some ornaments, a few cards, and more.
And although I showed this as a holder for swapping ATCs, I think it words perfectly as a gift card holder. You can find the post on Twisted Cards here and here. You can see in the second link how to adjust the folding to accommodate a sideways card, which would pretty much equal a gift card.
