Sources are...well, something I love and treasure. But I don't think you need to write the whole story of each item. Some sort of short-hand info; the original/source - material, provenence, date--your product - material, machine made/hand-made with authentic tools/power-tools. Something short and simple, just to give the customer an overview.
But then again, something like the parchment tablets which are a plausibly-historic-but-no-sources kind of item may perhaps benefit from a little extra info. But I'll be happy to give them my Modern Craftsperson's Seal of Approval (MCSA?)anyway! I LOVE the parchment tablets!
If you want a simple answer, you could you a 'rating scale' for historical accuracy (like Historic Enterprises does at the bottom of their item pages: http://historicenterprises.biz/gown-early-medieval-10th13th-century-wool-p-947.html?cPath=100_191) This could link to a full description as well...
Thanks for all the comments! I see that the tendency goes towards "tell 'em all" - so I'll think of a nice way to tell the story behind each object. Maybe I'll turn the "story behind" into a little sequel on this blog, with a new item each post, so they actually get done in an acceptable time - since I know some folks are waiting for the market stall pages...
Arachne, I'm glad you love them that much, and I'll gladly take your MCSA, knowing the things you do with tablets! I finally sat down yesterday night with my blue-pink band and started moving it to the new tablets (and I'm already over the middle...)
Hsifeng, I have thought about a similar "rating", but I have some problems with the concept. Historical accuracy is not always easy to grasp, and while it is easy to point out this and that not in accord with what we know today, where do you start to give the "five stars"? Is a hand-sewn garment made from machine-made cloth that is close to the original in thread count more five-starrish than a hand-sewn garment from hand-woven fabric - but fabric that is quite different from the original cloth used? Do you need historical tools for manufacturing a five-star item regardless of whether that can be seen later? And how is the customer supposed to know whether the shopmakers criteria for "five-star" are similar to his or her own criteria? Perhaps to the customer, hand-made with historical tools matters much more than the actual sort of wood for a spindle, but the vendor sees it the other way round?
