Hi Mike,
The first frame is the hardest, it takes a while to get familiar with your tools. The bandsaw can save a lot of sanding when you stay close to the outline. When you are using the Dremel on the inside of the frame use light strokes quickly and you will avoid lumps and bumps, with a little practice you will notice a nice improvement in the surface of the frame.
You are off to a good start, only 8 more frames to go.
Mike
