Kathy, I don't have the totals of each fabric for the pieced swags, but trust me...it's not critical!!
Because there is no way to know exactly how everyone is laying out their fabrics, everyone's version of the exact yardage needed will be a little different and that is why Sue has us making just a few of the pieced swags each month. This way, smaller scraps can be used for them.
If you don't have enough to follow Sue's directions exactly for the color placement of the pieced swags, don't worry about it. All of those units will be mixed up when the quilt is assembled, and you can really use any fabrics for them. Just try not to put two pieces of the same color right next to each other and you will be fine.
If you are concerned about running out of the ombre, just don't cut any pieced swag pieces from it, and save it all for your leaves.
