I saw an ad in the McCalls Quilting magazine for an app for the ipad or iphone that enables you to "audition fabrics and colors" in blocks. I went to the website, QuiltersApp.com, listened to the video for the iphone, which is what I have.
Evidently you can load photos of your stash into the app and use the inventory of blocks in the app to place fabric choices into the various pieces of the block. You can add sashing, with or without cornerstones, too. You can turn blocks on point and add setting triangles, also. It really looks awesome. It costs $20 for the phone, and I think it's $25 for the ipad, but I'm not sure. I didn't pay as much attention there.
Has anyone bought this?
