I was getting ready to throw away an old cheap glass-top patio end table when my wife came up with the idea of covering it in pennies. Since I really hate to ever throw anything away, it naturally seemed like a good idea.
Step 1: Gather your supplies
Second, I used an adhesive that works on non-porous surfaces (I used Goop, but other similar adhesives should be fine).
Third, I didn't count them, but I probably used about $4 worth of pennies.
And finally, I used grout. I happened across a pre-colored bag of grout that was marked down substantially, so this worked for me.
I also used some cleaner to clean the table, a putty knife to spread the grout, and damp sponges and paper towels to apply and finish the grout.
Step 2: Start gluing
After gluing down all the pennies, we let the glue cure per the manufacturers recommendation.
