Unfortunately, I couldn’t salvage the two short pieces and I didn’t have any extra molding so I had to go back to Home Depot to get one more piece. I marked the pieces again – more carefully this time, and cut the last two pieces. The most frustrating part is that it is exhausting for me to cut these pieces by hand in the miter box so I was upset I wasted all that energy on those three cuts, ugh. But at least I got the pieces cut correctly this time and then I just sanded down the edges a bit so they were nice and smooth. I think they fit together pretty decently.
