The heart magnets and the gift tags are very cute! We've used them to make sleds (although we did them so that the sticks were runners on a toboggan style sled similar to this
), boxes, coasters, doll houses.
We also would glue them to the outsides of a pickle jar or whatnot as a pen container, vase (with holes punched in the bottom with a nail), etc etc.
Would make fences and "jumps" for our breyer horses.
Beds for small dolls or stuffed animals. [URL="http://www.makingfriends.com/beniebed.htm"[/URL
The rudolph christmas ornaments or christmas trees were also super popular. Just make a V with 2 popsicle sticks and put one horizontally across near the top. Little red pom pom nose, and 2 googlie eyes and you're all set. We'd put little bows and holly leaves up at their "ear" also. Super simple and very cute so great for little kids.
