Thanks Whittler. That answers my question about needing a clear coat before cresting. I had thought about staining the whole arrow blue then doing a white/blue crest, but I'm leaning toward leaving the wood natural. A white crown shows up great in the leaves and is what I've used as a base for all the ones I've created so far, but I'm thinking about something a little different. I was looking at pictures online to get ideas and came across one that looked really nice. It had about a 1" wide series of blue/black/silver cresting stripes at the center of the fletching, then about a 2" wide series of matching stripes a few inches in front of the fletching. Everything in between was left natural. Being for a 10 year old, I may end up doing the full white crown just for visibility and try the other way on some for myself later, but not real sure yet.
