Yes, that's what I used. Before you cry foul and get mad at me, I need to explain one more thing......
If you look close at the pictures you will see that there are 2 plies. I cut 2 identical pieces out with diagonal cutters, stacked them together and used a small artist paint brush to apply liquid model airplane cement between them while held together. Capillary action sucks the cement into the joints and glues them together......same with the styrene plastic bottom.....probably took 5 minutes to glue and for the glue to set....then and hour to dry to hold weight. Hint.....if you have a plastic supply close buy, get Weld-on 3 for the capillary gluing.....used for Acrylic (glues instantly) .....can use Acrylic for the bottom too, but styrene was cheaper and came from Ace Hardware.
Hmmmm, wonder what aluminum picture framing from Hobby Lobby would look like around them.
