I used to make jewellery in the days before internet sellling took off (1980s) and this is how I sold it:
I asked friends who had a market stall to display it on their stall - I paid a bit towards the cost of the stall hire. This can work well if you know anyone who will do this and you have an easy means of displaying your stuff.
I did lots of shopping research. I searched around for likely shops selling similar sorts of jewellery, gifts, crafts and clothes. Independent shops are best - not chain shops.
I took note of the name and address of the shop, went home, found their phone number in yellow pages and phoned up to speak to the manager. I outlined the sort of jewellery I made, askied them if they would be interested in selling some in their shop.
If so, I would arrange an appointment and bring along some samples. I found in over 50% of the cases the manager would be ok about having some of my jewellery to sell. The thing then was to get them to buy it from me as opposed to sale or return. This meant I had money up front and the shop had paid for the jewellery whether it sold or not. Shops of course will mark up the jewellery, so I had to sell it wholesale - about 1/2 - 1/3 of the retail cost.
So if you are scouting around looking at shops, you need to pick shops where you think your jewellery won't retail too cheaply otherwise the wholesale price you get will be tiny.
So look out for shops in upmarket or touristy areas - I found Brighton and Islington were really good, for instance.
I caught the train to Brightone one day with a box of jewellery I had made, went to some likely looking shops and sold the lot. Came home with over £300 cash on me! (this was in the eighties so seemed much more then). Liberty's department store in London is also a good place to sell to. I don't know if it is still true, but at the time, the buyers were happy to see unknown jewellery makers. They offered to buy some stuff of mine, but for too low a price. Wish though I had let them have it, as it would have been such a coup.
HTH and good luck!
