How can I attach a wooden grill to a glass kitchen cabinet door so that it is removable
You could use just a really small dab of either white glue or silicon. I mean REALLY small dabs of this stuff. It'll hold it for you and if you want to get it off later on, you'll be able to do it carefully. I think I'd use the glue first to see how it works before trying silicon. Silicon really grabs. You'll need to tape the grill onto the glass overnight, while the adhesive dries.
