I recommend to list 4 at a time, easier to keep track of, and be sure to post in the correct forum sections, Folders, Fixed, Customs each have their own sections for individual people.

Keep your list matched to the order of the knives in the photos.
I've seen some that will show a photo of the group and then subsequent posts in the same thread, one for each knife
As some may not recognize the various knives, numbering them would be a good way to show them, magic marker number next to each knife.
Clearly state the price for each knife and as the new rules of the forum, you need to state the complete price if you are going to use PayPal or something that has percentages, in other words you need to do the math as to how much you need.
Photos are key, show a few views of each knife, if someone needs more photos, add them to the particular post in the thread, don't scatter them throughout the thread.
A spreadsheet for yourself to keep track would be good, if you don't have microsoft suite of software, you can get the free OpenOffice and use that to keep track of the knife, cost, buyer's email/address
Good luck, it's been a long time Hugh Bartrug's name was mentioned in Bladeforums, I met him and Rick Hinderer many years ago at an Ashokan Seminar, it was nice to meet them both and to get to know Rick over the years.
