Those are nice David.
Not sure how you dye yours, probably when you stabilize the blanks but, when i dye my box elder, i do it on the lathe just like i do a ca finish. I use alcohol dye from hobby lobby. Drip the dye on top of the blank with a piece of cotton cloth on the bottom rubbing it in. Also, my BE is not stabilized so it takes the dye pretty good, not sure how well it would work on wood that has been stabilized.
