I let the patch lap over the quarter face while I welded up the inside edge, and made sure to keep that flush with the trimmed edge of the first patch.
Once that was like I like, I trimmed and leveled out the second patch and quarter, and welded that as I went. It came out alright but will need some filler at the bottom. After appropriate grinding and touch-up welds, I rattle-can etch-primed it because its humid out. The wind was working against me a little in my stall welding today, but I opted to keep fresh air and light coming in and just dealt with it.
