I have that pattern in one of my books. May take me a bit of time to locate it, tho.
ETA: OKAY, it's called "March of the Crabs" from the book:
"lots of scraps, it's time to quilt" edited by
Jeanne Stauffer & Sandra Hatch
page 88

a used hardcover is going for $4 + shipping at Amazon
The book is well worth the price!
