Hi there and good morning to ya. Here is a link to projects with diy etched glass.
They sell etching liquid that can be used on all types and sizes of glass products. You can buy it at any craft store.
HERE are several choices of glass etching cream.
You can use a dremel and outline a stencil or design on glass. Did that on a car window.
Here's a great tutorial that teaches you how! https://www.thekimsixfix.com/2014/08/how-to-etch-glass.html#_a5y_p=3941628
