Re: fly rod signature
Somewhere in the past...maybe 15 or 16 years ago I read/heard about a kind of tape from Scotch brand called 'Magic Tape' if I'm remembering correctly...and to put a sig and info on a blank, a piece of this 'Magic Tape' was cut from the roll with scissors (both ends) then placed on a clean piece of flat glass, written on, then peeled off the glass and placed on the blank.
Once the finish was applied, apparently the tape disappears. Kind of makes sense since white wrapping thread mostly disappears when the finish is applied. Could give it a try on a scrap.
