For those of you who haven't got your book yet, fabrics needed are:
2.5 yards for background squares
1 yard for narrow borders
2 yards for wide border (same as background)
2 yards multicoloured for the scroll design.
5/8 yard for binding
1/8 yard for sashing.
4 yards for backing.
BUT you have to remember that these quantities are for the quilt finished at 62in square, with 7in blocks.
I am doing mine with 10in finished blocks, so I bought 10 yards black, because any left over will go into my stash, and it's cheaper per yard from Hancocks if you buy 10 yards in one go.
I was able to get a multicolourd fabric for the wide border from a member on this board, though there were a couple of possibliities on ebay too. But it would be easy to substitute scraps, one for each scroll, so that you would end up with a multi coloured border
