I played a little bit with the Country Road Quilt Block:
I drew the block with a 7 x 7 grid.
It is a terrific chain block! Here is Country Roads set side by side in a straight set:
Rather than look for alternate blocks to pair with it, I experimented with deleting some of the lines in the block to create an alternate block.
The following quilt designs are all created from the Country Roads block and simple variations of it. All are straight sets.
I am sure that there are lots and lots of variations to this block. Take some time to play and see what you can come up with!
