Alas, I'm not Therese, so here are my cards, created for this challenge.
I'm making lots of Christmas cards at the moment, keeping them very simple as I need about 100 in total - some for family but most for my Club and to donate, so my next card adds to that stash.
I've used the tree stamp from the Christmas Tree set in Die Cutting Essentials, stamping with Versafine Onyx black onto vellum, and clear heat embossing. This was then cut with the matching die, as was the water coloured card behind, then the vellum attached over with the glue placed strategically under the stamping. More spatters from SU Grunge set. In real life, there is some obvious dimension, as the vellum curls up at the edges.
