I used a lot of different types of pens when I first started building bows. The calligraphy pens with India ink look cool, but are a learning curve to be artistic with. But the best ones I found are fine point paint pens. This is what I buy.https://www.amazon.com/UCHIDA-Color-Extra-Paint-Marker/dp/B06Y1MZ8QF/ref=sr_1_4?crid=2Z8YHQ9C3PDPP&keywords=deco+paint+pens&qid=1654959027&sprefix=Deco+%2Caps%2C173&sr=8-4It’s best to clear coat over your writing, but you need to be careful what kind of clear coating you use on a finished bow. DON’T use a spray lacquer…. That can be a nightmare and melt some clear coats. It’s pretty hot stuff. If it’s a finished bow I wouldn’t mess with clear coating over it. Just use the paint pen…. That’s the safest bet. Kirk
