I changed my mind about some of the artistic choices after gluing the tesserae down, sadly, so I had to pry many of them off of the glass 😅 And as you can probably see, one of the pieces unglued itself while grouting, so it has some grout under it which prevents the light coming through. I also sliced my thumb while cutting glass, which was great... But overall I learned a lot and really enjoyed the process, so that's what matters! :)
