Marking the frame outline The process itself was fairly straightforward. I placed the plywood sheet underneath the frame and traced the outline directly onto it. Once the lines were drawn, I cut along them using the jigsaw.

This widens the cut just enough for the blade to rotate smoothly toward the next side. Corners - widen the cut until blade rotates to the next side After cutting the outline, I pre-drilled all the screw holes and did a quick dry-fit.
