Once the glue has dried I proceed to rasp off the excess til near flush. From there I sand it down with progressively finer sand paper until it’s completely flush. Here I used 80, 120, 220, and 320. If there is a gap around the edge it can be filled with sawdust the same color as your wood and then covered in thin CA to fill the gap. That wasn’t necessary here though. This one showed some white streaking and I think came out pretty cool! Thanks for looking and hope this helps someone.
