So far so good. This is where it's at after two wipes of poly brew:



Lessons learnt so far:
- Apply before finishing (duh), because you need to sand back the CA. I had to sand back the poly and stain and do it again.
- Calcite crystal is actually crystal, not white, so the inside of the groove is the colour that will push through. Consider painting the groove first, and/or apparently you can stain the crystals.
- Scraping the stain off the inlay is fairly tedious.
