How did I get those spoons to stick to the glass surface? If you want to discover my secret, "stick around" and I'll show you.
Make sure to spread a thin line of glue. That is all that's needed. The glue will foam and expand in volume once applied. I used too much the first time, but that really wasn't a problem. After the glue had completely dried (about an hour) I used the flat end of a razor and scraped the excess glue from the surface of the glass.
I used thick rubber bands (the ones that are on asparagus bunches from the grocers) and the white "plumbers" tape to clamp my spoons securely to the glass. (Either of these or both will work beautifully!) Put the rubber band around the surface of the glass ABOVE where the spoon will adhere. Be sure to do this BEFORE you apply the solvent. Apply Gorilla Glue, slip the rubber band over the spoon and secure in place with plumbers tape.
I had to use pliers to bend one of the spoons that I couldn't manage by hand, so I wrapped tape around the end of the pliers so the surface of the spoon wouldn't be damaged in the process.
