These bunny napkin rings are so quick and simple you can make them at the last minute for your Easter dinner. They are made from constructions paper which is rolled and glued in place. Then you cut out the head from constructions paper draw on a face and glue it onto the tube. A pompom or cotton ball glued on the back for a tail completes the bunny. Personalize them by writing each guest's name across the feet so everyone knows where they are sitting at the dinner table.

I've never tried it but I would think you could also make them from craft foam and use a hot glue gun to glue them in place. I'll have to try that.
