The one I made recently used 2 jelly rolls plus 6 FQs of just the lights of that collection. I originally purchased 3 jelly rolls and I used a few of the third, mainly the lights, because there just wasn't enough of those.
I think when I do it the next time, if I was going to use all patterned, I would get one jelly roll of all lights and one of all darks, and one mixed if possible.
This is why I want to get two jelly rolls of the patterned and one of white. The Nature's Chorus has several fabrics have a lot of white background so it might be OK to mix them in with the all white. If it doesn't look right I'll get another all white (maybe just get it anyway since I can use leftovers with most anything).
I didn't cut off the pinked edges. I measured and from tip to tip of the pinked edge is 2 1/2". Line the pinked edge up with the 1/4" foot. It didn't matter that much to me because I squared them all up anyway. It makes a large log cabin block with the 2 1/2" strips and it only took 36 of them for the quilt.
