Yeah Tony, I have a hard deadline on this one and haven't made the first bit of sawdust yet so I figured I better sit out the swap.
I appreciate all the comments on the flag fit. I'll just go with my original plan. If the divider piece slides in nice and tight and the lip on the trim pieces stays tight at the miters, I'll still leave it loose but if not, I'll just glue it in place as planned and have confidence the flag can be inserted without issue. I didn't mention it but my BIL has a bad case of OCD. As in he vacuums his car EVERY time he gets out of it and washes the dishes AS he unloads them from the dishwasher. So while he'd never say anything to me, if the flag doesn't fit perfectly or there are gaps in the miters, it will drive him bat sh$t crazy. Now that I think about it, maybe I will intentionally make the miters a little gappy in one corner 😂
