The Thanksgiving card did not have any stamped images. I used some awesome cardstock that I don't remember the name of. Maybe this weekend I'll be able to uncover the rest of the sheet and update this with a name.
The Winter card uses stamps from Purple Onion Designs. The artist is Stacey Yakula, and boy, does this gal have talent! Everyone of her stamps is cute and works well together. I used Birch (Winter Bunny) and Snowy (Winter Owl) from her "Winter Wishes" collection.
In order to get a snowy look in the background and the foreground, I heat embossed snowflakes onto transparency film, which held up really well to the heat. (I expected it to warp or buckle, which it didn't do.)
Sometimes I wish the ideas that pop into my head were less complicated than they turn out to be!
