So here is a photo of the finished urn for my friend's dog. It's about 5.5" x 6.5" and about 4" high. Mahogany with Sapele splines and Oak top. As you can see there is a sliding panel in the bottom that will be pinned in place, once the ashes are inside, with matching splines and will not be openable. Finish is Minwax wipe-on poly-many thin coats. I sent them a photo and they are pleased. I don't do much flat/square work because I don't do it very well, but I am happy with how this came out. I did a test piece/mock up 1st to check my processes and am glad I did. I built a jig to do the slots in the miters on my router table.
