This file comes with the wreath base, the leaf pieces, and the pieces to build the flowers. It is compatible with both the 8x12 and 12x12 mats. Note: The file comes sized to fit the 8x12 mat but can be enlarged (make sure you leave it all grouped) to have the wreath base fit the full 12x12 mat. You can find additional images and a full tutorial on my blog: http://jamielanedesigns.blogspot.com/2014/11/3d-paper-mum-wreath-and-fall-wreath.html
