The 148th birthday of Laura Ingalls Wilder - the author of "Little House on the Prairie" - was celebrated by Google with figures made of wool.

And here's the yarn behind this Google Doodle – and it's a Doodle of a yarn.

Jack and Holman Wang were tapped to be the "guest artists" for this Laura Ingalls Wilder homage (Actually, they were invited more than a year ago, but were upstaged by the start of the Sochi Olympics on Feb. 7, 2014). 

In their blog, the Wang twins describe their inspiration. 

The Wang brothers are from Canada. Jack Wang is a writer and associate professor in the Department of Writing at Ithaca College in Ithaca, New York. His bio says that he's currently serving as the David. T.K. Wong Creative Writing Fellow at the University of East Anglia in Norwich, England.

Holman Wang says that he "downshifted" his life from corporate lawyer to children’s author and illustrator. Since late 2012, he's worked "full-time as a children’s author and illustrator with, ironically, a toolkit of entirely self-taught skills in needle-felting, model making and photography."

It's the last bit - the needle felting - that apparently caught the attention of Google. 

The brothers describe the process for creating Laura and Mary out of wool felt on the Google Doodle blog. 

After their little felt stars were created, the illustrators built a faux prairie backdrop. 

And then Jack built the requisite log cabin out of sticks.

The scene was set up outside in January and photographed. The Google clouds were digitally added later. 

If you're a fan of this unusual hand-crafted illustration, there's more coming. 

The Wang brothers have a new series of felt illustrated books, "Star Wars Epic Yarns," due to be released on March 31, 2015. Each book contains twelve iconic scenes from the Star Wars movie franchise. "Jedi apprentices and little princesses will delight in this (heart)felt retelling of the Star Wars saga," according to the Wang brothers.
