Yep, and that's a VERY good rule
Personally because I'm lazy and it conveniently gives you more 2 1/2" scraps to put in your scrap pile, I'd do the sashing the same width as the jelly roll fabrics, but if you need to fill out or take in the size a smidge you can use whatever you'd like.. no one is going to take a ruler to your finished quilt and ask why you didn't opt for "_" width sashing.
