What sells the best? That's a hard one to answer. Look around the area at other craft shows/fairs to see what is being sold. That could give you an idea. Also, something unique could work too
What kind of prices work and make people want to buy?
People in general don't have a clue as to what goes into making things, especially quilts. They don't understand the price of the fabric, plus the price of your time that you have put into the making of the items. I had a small baby quilt at a craft fair. I priced it at $50. The fabric alone was almost $35(included batting and backing). There was a lady who was interested in it who said it was too expensive and would I take $20 for it. I politely told her no.
What are some good resources about it?
That one is a hard one to answer. Maybe talking to people at craft fairs and asking them. I don't know of any books. Or, maybe do a search on the internet?
Where is the best place to sell?
Again, this is a hard one to answer. All places are different. If there are gift shops in your area that sell local wares, try there.
Where to find out where to sell in my area?
Same as the above answer.
Should I look at learning something outside of quilting?
That's an option up to you. Everyone is different. I know there are ladies/gents here on the board that also knit, crochet, cross stitch, etc. It's up to you if you want to learn these things. Will those items sell if you put them up for sale at a fair? I don't know. It's worth a try.
I did a craft fair last November. I made these little mice with candy canes. 75 of them. Sold every one! I also had table runners. Sold all but 2. I had 25 tote bags, really pretty and distinct fabric. NOT ONE SOLD!! We all thought for sure those would sell like hotcakes.
I also had a couple quilts....was told the prices were too high. I had some embroidered towel sets. I only sold one set, but that was when I brought the price down and didn't make any money off it...I broke even on that. My BIGGEST seller was the fabric books. Those sold like hotcakes and I sold out.
There were other people there that has hand crafted items like I did and they pretty much sold nothing. There was a lady who had hand crocheted doilies which were VERY pretty. She sold none.
What I had that was unique was the tote bags (didn't sell--priced at $20), the fabric books (priced at $12), mice were $1, so those I knew would sell. The towel sets were VERY unique since the embroidery that was on it is a hard one to acquire (towel, washcloth and hand towel-$40 set)
I hope this helps a little.
