This won't be answered in the order asked ...
By all means, build your Christmas rods, or gift rods any time, the way you think they'd like them!
I don't use CP. I like the really deep, jewel tones I get when the epoxy is applied.
Be really careful if you try to slice down a run! It's so easy to slip and scratch the blank. Use an emory board! There are so many different "grits" available (beauty supply store), that you can smooth the drip down, and even finish it off (mostly) with a fine silk grade. Then run a really light finish of epoxy over it.
If you use a "Power Zap" cauterizer to cut/burn your thread close to your wrap, it minimizes the "fuzzies".
I, too, use calipers to get my wrapping "exact". I may be far too AR to properly build rods, but it's sure not stopped me yet! As many times as I re-do the wrappings I've gotten pretty good at them!
