Ron - actually I put a dab of glue in the center of the short side, and then the space balls (cut in half as my groove wasn't so deep) in the long sides. I figured the space balls would allow for wood movement across the board, and the glue would help with positioning.

Lighting makes all the difference, especially with highly figured wood.

The first urn I built was mine - figured I should just make what I like (simple walnut).  Having faced all the decisions most recently when my dad died, well, just felt like my urn could best be my choice. Then my husband decided he wanted me to build his. Shared that with my friend, and that's how the third one happened.  Building the case for my dad's flag was a project that was quite emotional for me.
