Has anyone here worked in this wood?


I have limited experience. I only use small amounts for marquetry, small
carvings or inlay accents. I consider it a softer hardwood. Easy to work
by hand. Glues and polishes well. Little to no warping in thin slices.
Use a UV blocker in your finish or it may/will darken. Has consistent
color for inlay patterns and marquetry. I can cut from two boards and
still get a good color match.

I prefer patterns in large surface areas, grain or inlay. Used alone, I
personally find Pau Amarillo plain for it's cost. The grain is usually
visible so I can't use it as a flat color is larger sections like holly
and other woods. I use it to extend my color palette for inlays and
marquetry without dyes or stains.
