Why not get an Etsy shop to start with? There's no up-front money to pay, and it's easy to do. I have my own website, and sell on Etsy, Craftsy and YouCanMakeThis. I make a lot more on the other websites than I do on my own website. Everybody knows about Etsy, Craftsy and YouCanMakeThis, but not too many people know about my little business. They do the advertising for you, as well. On Etsy, you can set an additional advertising budget, and they will promote your shop more, if you select that option.
And you may want to get on Ebay to sell your fabric. That's the first place I go when I can't get the fabric I want locally. And I know a lot of people who do the same thing.
Civil War reproductions have always been a great seller at the shop where I work. And we sell a lot of Civil War quilt kits, too. If you could use the fabrics that you have, and put kits together for them, I think that would be a great seller for you. 30's reproductions haven't sold well for us in the past few years.
