This is a fun and simple project, also a little addicting. My daughter and I etched a fish on her fish bowl this weekend. I have seen people put their fishes name on before but we tend to go through a lot of fish.
Out of vinyl cut your design, place it on your project
You will need some Armour Etch (Glass etching Cream) found at any craft store.
Use a stenciling cream to apply the cream to the exposed glass surface,
Leave it on for 5 to 10 minutes then wipe off.
