I'm making one now for me...have had the fabric for a couple of years...it does take a lot of fabric for a king size..i have used 2 jelly rolls so far, plus the yardage for the centers of the blocks and the footballs (I call them this)...I needed 197 footballs for a 9 X 10 king size quilt..I have 180 done so far..will start putting the blocks together before I finish up the number of footballs..I don't want to have any left overs...I make 10 footballs a day...the fabric I'm using is a discontinued 1895 hand painted batik called brown sugar...love it..I don't think I will make another DWR...I made the first one for my oldest daughter in purples and green...I am leaving the scalloped edges also..
Good luck with yours, I have and use the Sharlene Jorgensen's templates and pattern book..
