I haven't done it but I don't see why you couldn't birth it just fine. If you left the middle circle for later then you could pull it through that hole to birth it. Agree that you should cut the batting close and clip any inside corners or curves to make it lay flat. I would probably lay my bat down first cut larger than my plate, then my backing right side up (wrong side touching the bat) then my plate right side down. Once stitched all the way around I would trim the back and batting away and turn. I would probably also top stitch close to the edge once I got it turned to make the edge more crisp but at this point not sure on that point. Good idea for a table topper.
