I'm about to start a jelly roll quilt and have watched Jenny's tutorial. I was wondering if everyone does like Jenny and just takes the fabrics off the roll as they are stacked or do you mix them up. I have a Christmas jelly roll that I've had for a while and all the reds are together and the greens and so on. This is my first jelly roll quilt and I don't want to mess it up. Any advice would be appreciated. Thanks.
