I went to the website to download the free pattern: http://www.modabakeshop.com/2013/10/lattice-bones-quilt.html
I used a Bella Solid - Snow jelly roll and the Spring House jelly roll, both by Moda.
Here is the progression of the block:
The jelly roll is already cut at 2 1/2"
Cut from the print jelly roll: 2 - 6 1/2" rectangles
and 2 - 2 1/2" squares
Cut from the background jelly roll: 4 - 4 1/2" rectangles and 2 - 2 1/2" squares
The outside columns are easy to sew:
the background and printed squares are sewn together and the 4 1/2" rectangle is sewn to the printed square. The length and width of the block is 8 1/2."
the outside column to the center.
Pin carefully to be sure that the point
meets the seam of the printed square.
