The Paper Arts site talks about everything related to paper including stationery, scrapbooking, and DIY paper projects.

Ok, so maybe this is more of an item for kids. Still, it’s a good way to get them involved in the holiday spirit and give them something to do while you’re running around trying to get the house ready for guests. This is the Make Your Own Holiday Cards package from Made By Hands. It features 10 note cards with matching envelopes and a host of different pop-outs that you can affix using the glue stick provided.

The cards look colorful, and the pop-outs look decent - although the more creative little ones are going to want to skip the pop outs and make their own to glue on. Not sure about the recommended age range on these.
