Here is a recalculation of fabrics needed if you want to make the quilt larger, with the additional blocks, borders & swag. This measurement is for 94" square.
background increase to 9 yards
swag material (use whatever color you want, in example it is the dark blue) 4 yards
dark green for vines, increase to 2.5 yds.
everything else is about the same, if you want to increase any of the flower fabrics add another 1/4 yard to each color to be save.
Binding & backing are not calculated in these yardages, so I would suggest a yard for the binding and 10 yards for the backing to be safe.
If you want to do a scallopped edge on the quilt, I would bind the quilt in the same fabric as the background. If you are not, & are doing a traditional straight edge, you can use any color you want, maybe the same color as the swag.
