- My first tip is not to make informal arrangements with people. Use established venues that assure buyers of a trusted transaction.
- My second tip is to sell online, not locally in a consignment shop. You'll sell faster and get better prices because your market is a niche market who misses old-fashioned crisp sheets - and there are more of those on the Internet than in your direct region.
- You can sell on eBay.com. That is the first place I'd recommend trying, because there are a lot of interested buyers, it's easy to set up an account, you can sell on both a small and a large scale, and there's a lot of community help and support. I used to sell my original jewelry on eBay and I have sold other collectibles there as well.
- You can sell on Etsy.com. That is the second place I would go, because it's a nice user interface and I've bought from there repeatedly and found their help section the clearest of any selling website ever. I haven't sold anything on Etsy, but it's on my radar.
- You can sell on Amazon.com as a third-party seller, believe it or not. Their rules are fairly stringent and it's a bit of a learning curve. Not really for the casual seller. Not good for selling sheets that have been used, just for true "new old stock."
- You can sell on Rubylane.com. This is more of a commitment and business investment. I used to sell my jewelry there, too. It's not for casual selling.
- There are other websites - many of them - but I have no experience with them and so cannot recommend them. There are a lot of potential problems with newer shopping venues, and I tend to be very selective.
I hope that helps start you off if you happen to be one of the lucky ones that has a supply of those old cool cotton sheets we all used to use. Good luck!
