Another quilt that has captured my imagination was this Navajo-inspired log cabin design. It seemed easy enough to make up with just squares, and some gingham + black has provided some funky inspiration:
|Wide Quilt Backing in Black + Printed Gingham Linen|
|Wide Quilt Backing in Black + Hill Farm Gingham|
And here's the line drawing: 25 x 29 squares:
That's 725 squares: 344 gingham squares (47%) and 381 black squares (53%). So I will be ordering 5 yds of 108" black backing for the the black squares and the back, and 5.5 yards of 44" gingham for the other squares.
