Start with a store-bought grapevine wreath. Pick an odd number of white mini pumpkins. Attach pumpkins to florist picks, and then work the picks into the wreath, making sure to space them evenly. Secure pumpkins to the wreath with wire. Using additional florist picks, attach seasonal greenery (we used smilax) and bittersweet (available at your local garden center), filling in the spaces between pumpkins. Add an assortment of fall leaves to wreath with picks and wire for a colorful finish.
