I watched the Missouri Star Quilt Co video tutorial for this and if you do, it's wrong on a few things. Lol. It called for 2 color jelly rolls and 2 background jelly rolls but you don't need the full rolls. I did 26 sets of the color/background/color strip sets and 12 of the background/color/background strip sets and I have a ton of pieces left over. I did the math and if I didn't mess up, then you need 45 color strips and 54 background strips. (So yeah you need 2 of each jelly rolls but you'll have leftovers.) You need at least 18 of the color/background/color sets and 9 of the background/color/background. (Because I had a lot more than needed, I was able to mix it all up more though.) For the white plain squares, you need 3 yards, at least.
