The challenge didn't fit with any of my backlogged projects, so I settled on another postcard. To keep from getting bogged down with too many blocks I looked at only 4-patch block patterns. Then I pilfered the pile of black-and-white scrap from my current Midnight Garden project and got to work.
My original plan was six two-inch blocks in the black and grey. I
fiddled with it and got most of them stitched together... and that's when
things went off the rails.
