Hero Arts - unfortunately discontinued, but the Color Layering Christmas tree stamp is very similar. I stamped it after colouring direct to the rubber with some Zig markers, then spread the colour on the watercolour paper with a water brush. I then stamped the same image over the top to add back in the detail that was lost with the water.
I die cut the star from the top of the tree, and added a Copic coloured piece of vellum behind the negative space. I also gold embossed the sentiment on vellum and wrapped it around the watercolour panel.
HERE), I attached the decorated panel to the card base using foam adhesive tape. This worked great, but I found that when I lit up the card, you could see where the foam tape was behind the panel. I tried a different approach with this card - I attached the watercolour cardstock to a piece of red layering paper from Hero Arts, and I die cut a larger star behind where the smaller star is on top of the tree. I then used two layers of fun foam to raise this panel up on the card base - I just cut another star in the fun foam, and a square in the bottom right corner to make room for the battery housing.
Here's a little video:
