The art of origami is becoming popular amoungst crafters (I know the wife is one). I can well see the domain being used by a publishing house or crafts manufacturing company, in either case you will be comfortable getting $5,000 - $7,500 without a problem.
I would think therefore that in the domain trade you should look at turning $1,000.
I also did not see the Sedo auction, so hope you got a good buy.
Very nice name with good prospects for niche development.
