Here's a cute creature that's easy to make and the children will love! Just wrap 4 chenille stems (which back in my school days were called pipe cleaners!) around a lollipop. Then use glue dots to attach googly eyes. Photo source found via Frost Me here.
Or find a spookatcular way to package some store-bought candy. This package uses takeout-styled boxes (you can purchase from OrientalTrading.com). Use either foam stickers or card stock cut-outs for the face. Parents magazine gives you the bat wing template here.
And don't forget some of the easy lollipop ideas I've given you on Home Confetti's Facebook page. The Tootsie Pop Pumpkins (see here) and these sweet ideas here.
