Crafting a themed paperweight for a holiday or special occasion can be simple and easy with ready-to-use embellishments available at your local craft store.
This paperweight design required a scrap of decorative paper, as well as a few dimensional sticker embellishments (Jolee's Boutique, Funny Pumpkins).  The paperweight kit style is the Large Rectangle (PhotoWeights: Large Rectangle).

Before you begin your project, be sure to clean your paperweight with a streak-free glass cleaner.
The adhesive mounting board (included with each paperweight kit) was covered with decorative scrapbook paper.  The paper was trimmed around the edge of the mounting board.
Arrange your embellishments as you'd like and attach them to the background.  (The pumpkin embellishments shown are self-adhesive stickers).  The small pumpkin I placed on top of the two larger pumpkins was secured with glue.
After you've finished attaching your embellishments, allow any adhesive to dry completely before placing the mounting board face-down into the recessed area on the bottom of the paperweight.
To finish, place the adhesive bottom pad (included with each paperweight kit) over the bottom surface of the paperweight.
