I got the Dear Jane software and found Civil War Reproduction fabric bundles on eBay specifically put together for Dear Jane. The fabric is 200 different 9" x 11" cuts from seller 40yearhoarder on eBay. I got sets #9, #10, #11, and #12.
I also got an entire bolt, 15 yards, of Kona Cotton in Ivory for the background. The Kona was only $3.79 per yard at Fabric Direct but you do have to buy it by the bolt. That's a great price and I have found it to be from $6 to $10 per yard at other online retailers. Nice resourse for the staples in a fabric stash or if you want to go in together with friends and buy bolts.
