Well - I learned a new lesson - don't use a Sharpie to lay out your bow on the back of you bow. The lines laying out the profile of the limbs are OK because they end up getting scraped/rasped away. Lines drawn perpendicular across the limb/ bow, and left for any length of of time will leave a stain that won't come out. The black color will scrape off, but it will leave a line. I've worked on the lines, but I was afraid to be too aggressive for fear of violating the back ring. I'm hoping it will all turn the same amber color over time?
