This Pumpkin Wreath is compatible with both the 8x12 and 12x12 mats. This file comes with the wreath base (I cut this twice, once with chipboard and once with card stock and adhere the two together), six pumpkin petal boxes, stems for each side of the pumpkins, leaf pieces, and pieces to create the twists. Cut as sized, the assembled wreath is approximately 8-1/2" round. This can be made larger with a 12x12 mat.
