If you can't find anything on the bay, beau ties ltd is a great company.
As my moniker would suggest, I am a confirmed bowtie wearer and recommend them heartily. I have backed off on purchases, mainly due to cost - my secret source in the past was Filene's Basement, where a bowtie could be picked up for about fifteen or twenty bucks. They recently went out of business and I am having a hard time getting used to paying huge amounts for a little scrap of cloth. Luckily I've got a bunch already, and a good friend recently gave me a handful of vintage bowties (thinner) so I've got enough for now - until I find a stash for cheap, at which point I will grab some more.
FYI Beau Ties Ltd. is having a nice sale, and their usual volume discount still applies!

Thanks, Mark, 4 more on the way. Has anyone ever called you an enabler?
