CJ -
I'll post my two cents worth, but with the caveat that it's probably worth less than that - because I don't sell any of the things I make.
If selling online like Ebay, price it high and walk it down in price until it starts selling. It may cost you a few dead auctions to find the price point the market can bear. Also, if you see something like the coin caddy project going as a finished product for $25, don't waste your time trying to compete with that one, do something else. You may be up against someone that is just trying to recoop cost and is basically doing it for the enjoyment.
If selling in a retail environment, like a store, craft show or fleamarket booth - you have a wide range in what people are going to be willing to pay. I would imagine it would be best served to have a few different items in different price points. You may not hook someone willing to drop $75 for that worth-it jewelry box you make, but maybe you find someone willing to pay $50 for a coin caddy project. Or even lower you may find that you sell the heck out of little notion and sundry boxes or generic plaques for 10 or 15 bucks all day long. You never know what people have in their pocket and are willing to part with, like everyone says the economy is pretty much in the toilet right now and you have to remember that $75 is someone's water bill or food budget for the week.
Also - with Father's Day around the corner, projects like Dad plaques or Bar plaques may do very well. If listing online make sure you use "Father's Day" in your title so the lazy ones like me can find it
Either way, I hope you find a good market and selling point, and make a ton!
Good luck,
Craig
