I think my favorite cartridge this holiday season was the Winter Frolic cartridge. When I bought it last year, I envisioned making layouts and did make a cute little mini album. (Opps, just looked back and never photographed it. Next time I dig out my holiday albums, I'll try to correct that.) Anyway, I haven't made any full-size layouts but I have made a number of cute, super-simple cards like this little mouse.
