I cut the two layers of the window out of 0.044" chipboard, painted them with black gesso then dry brushed with copper metallic paint. Glued together and then glued on to background card stock. The branches of greens were done using a paper punch, and I 3D-printed the deer on my resin printer.
Those are lovely! Thanks too for the design link to the cathedral file link. I’ve been wanting to design something like that - but haven’t gotten to it yet… this is better!
