Merry Christmas to you and yours!

I have been making some ornaments with purpleheart. I have been researching all over on how to bring out the purple color. I have seen a lot of people using heat, others using UV lights, and others using the sun and acetone.

My question is: how have you gotten the color to come out and what finish did you use to keep the color?

On a side note. I use key chain kits instead of Ornament kits. I give them as gifts so this keeps the cost down. This year I also used them as little urns. Adding the ashes before pressing together.
