As mentioned previously, the new apron will be made up of 3 layers of "octagons" with the middle layer rotated 45 degrees relative to the top and bottom layers. Here is some of that stock being mitered on the table saw. It's really nice quartersawn white cedar.
Here are the old aprons that I'm replacing with a one-piece, brick laid apron, faced in quartersawn cherry. Bye bye old aprons.
