To answer the questions about the trim, it’s just a thin moulding I found at Home Depot, in the moulding department. It was one of the smallest ones sold, all made of wood. I can’t seem to find a picture anywhere on the net but I promise, it’s at the hardware store. And it’s pretty inexpensive, I think 5 dollars for 8 feet.

The squares on the corners are slices of a square dowel, also from Home Depot. I just bought a dowel for maybe 2 bucks, then sawed it into thin little pieces. After everything was dry, I just used glue to attach. I felt everything was too small and fragile for the nail gun.

Thanks again ya’ll!
