Thanks for the answers everyone.

The ribbons are indeed fixed and do not serve to size the hat, which is sewn to size. They are proportionately about the length of the ribbons shown in Panache's posted photo (thanks Panache). They're long enough that when untied they'll touch the tip of my chin when the breeze blows from behind. However, I find that's too short to tie a bow that leaves what I feel are pleasingly proportionate laces hanging down.

I also appreciate the advice from Thompson's book (thanks cajunscot), but I wouldn't know a seam ripper stitch from twizzlklantles if one bit me on the buttocks. Besides, that all sounds rather permanent, even destructive.

This is the best image I've been able to find of how some might tie their knot.

Very nice (the powder blue color notwithstanding), but I like Panache's free-flowing style better.

I'll post some snaps in the appropriate sub-forum once I get some film in the ol' digital camera.

Thanks again everyone for your help.

Regards,
Scott Gilmore
