Make — stained glass

My grandmother likes to collect rocks and gems. She displays them in bowls around her home, and I always love admiring her collection when I visit, especially the agate slices she has carefully propped up on various shelves. I’ve been wanting to start my own collection of these slices for several years, but only recently found a simple way to display these slices as stained-glass-inspired wall art, or in the window as a suncatcher.
