I think I've seen a quilt made with 16 FQs is called Sweet 16. I got a 20 FQ set of Sweet & Sour at Connecting Threads when it was on sale for $20. I did this design for it yesterday, leaving out the 4 white FQs. I ordered 7 yards of the floral for the flowers, sashing, and backing, and a yard of the dark purple for the binding.
It's 58"x72" and though EQ6 says it needs 5/8 yd of each fabric I think it over-estimates. I should be able to get out of each FQ two 8 1/2" squares, one half-square for the edge, three 2" sashing blocks, and 8 small flower petals.
These colors are what her bedroom is done in. :D
