It's funny that you should post this now. I too was all hopped up to do a DJ quilt. Started collecting fat quarters and some half yard cuts. I don't have quite as much as you but still have a good amount. I didn't buy my sashing and background fabric yet though. Phew! Anyways, after looking over the DJ quilt several times, I started losing interest. I noticed a LOT of the blocks were applique, and due to their size would have to be done through needle turn. I like working with my machine and really have no desire to do a bunch by hand. So needless to say, I lost interest in Jane rather quickly.
Like you I now have a bunch of Civil War reproduction fabric that needs a project to go with it. Last night I was looking at the book The Civil War Quilt Diary. It has stories and letters that go along with the 121 blocks in the book. Most look like they are pieced which appeals to me much more. There's another book, The Civil War Love Letter Quilt, that also has 121 different blocks and contains love letters sent during the Civil War. I think a lot of those blocks are paper pieced though so I probably wouldn't want that book. I very well may get the first book though. I searched all evening through lots of patterns but none really appealed to me. I'm pretty certain I want to do a sampler of some sort. Just haven't found the perfect one. :)
Good luck with deciding what you'll do with your fabrics!
