First of all, I would like to thank everyone for the comments. You folks gave me a lot to think about. I'll try to hit all of the suggestions left for me;
Sorry for not having my location in the post, I overlooked it. I am from southern Ohio, just outside of Athens. The school district is pretty rural, not a lot of disposable income.
Les L, for the kids is definatley on the top of my list. Attaching the card to the item is a great idea.
Steven NY, that is awesome to hear about your bread business. That is what I was hoping could happen from this event (doubltful that it would be on your scale though!).
JHCC, I couldn't agree with you more about the practice. The good thing is that this would be practice with a purpose.
Frosty, you bring up great points about the insignificance of the material expense. I am overthinkinig cost, especially given the fact that most all of my material is drops from steel suppliers that I can get on the cheap. Propane is my biggest expense, but that has a lot to do with my son (11 years old) as my forging partner ( he is the "A" in DNA metalworks, kind of a play on our initials (Aiden) and that he is my son). He tends to heat, beat, and repeat way more than neccessary! But the experience far outweighs the cost. I'm not as fast as you are with cranking out products, but I am getting quicker. And as JHCC said, this would be great practice.
Kozzy, I like your horseshoe project ideas. I will check into the cost. I will check into personalizing on site, I'm sure that would be a great selling point. The welded projects are on my radar also. My son is the welder of the team, he is actually a better welder than I am. He just made a cat face out of washers, nuts, and nails for his little girlyfriends birthday. I will post a picture when I get a chance. It really came out good.
Glenn, thanks for the ideas. Stocking hooks... at a christmas sale, why didn't I think of that? That's why it is good to ask for advice, I get stuck in the same products and don't see the obvious ones in front of me. Thanks again.
George N M, I would love to do the nail swords (especially since I feel like I have 100's of them sitting around. That was one of my son's first project for hammer control), but I don't think the school would let me. A few years back, he drew a picture of a hunter, and they made him cut the gun off of the picture. I am going to check though. I have the hair decorations on my list too, thank you.
Sorry for being long winded, just wanted to show my appreciation to the responders. I guess looking at everything, the biggest con that I didn't list is fear of failing. That one should be on the top, but is hard to admit. I've have not done any craft shows yet, let alone for kids. I think my stuff looks good and everyone else that sees it thinks it is good. I will be submitting some of my work to the organizers for approval, so I guess they will tell me for sure whether it is good or not. I probably just need to suck it up and try to do it, stop overthinking everything. Thanks again for all of the advice.
