At the moment, I suspect that W.O.T.M stands for Women Of The Moose. According to their website, the Moose organization is a fraternal order first founded in the late 1800s but "reinvented" about 1906 to "provide protection and security for a largely working-class membership" in case the bread winner died, i.e. the husband.
The women's auxiliary was formed in 1913. The focus of the group changed a bit after WWII. There are still many active chapters across the US today. I am in the process of trying to track down whether or not there was once a chapter in Colville, Washington.
Some of the embroidery on the quilt is difficult to read so the spelling of the names on the quilt are subject to interpretation.
I would love to be able to document any information about the women listed on this quilt and discover why the quilt was made. If you recognize any of the names or can help shed light on this quilt's history, please email me.
I look forward to hearing from some of you!
