I found a jelly roll but the photo is a side picture of it rolled up so I have no idea what the fabric would look like.
FiveseveN- thanks for the tip. I have scrapbooked a few years back and used that method. I didn't even think about a coffee type staining process. Will have to try that if I can't find something already made.
I'm so excited about my idea. I just hope that when it comes to fruition that it will look as I've imagined it!!!
