Encyclopedia Britannica says this about that:
I found all these while checking out this free pattern - A 3-hour baby gingham quilt.
from The Jolly Jabber - the news feed from The Fat Quarter Shop. But, here's a heads up....there's a video too and if you watch it, you won't need to download the free pattern.
***********I amend this post to include my version of this baby gingham - but rather than gingham, I used The Rifle Paper Co. fabric off the shelf. I also added amended the pattern to add a row of light to one end of the light/medium strip set and a medium to one end of the medium/dark strip set. I like the balance around the quilt. My quilt has 11 blocks across and 13 blocks down for a finished size of 55" x 65".
