Even though my mother has been gone now for six years I still miss her terribly. :(
12/27/2010 - Thanks to an anonymous commenter....the mystery pattern is identified: "Envelope Afghan" :) The pattern can also be found on Ravelry as well! If you do a google search you can find lots of other sources as well. What I find interesting is that the reason why it is called envelope afghan is because the pattern had been previously passed from person to person on the back of an envelope. That probably is why I was never able to locate the pattern is my mothers knitting things. I'm going to look one of these days to see if I can find it...when I have some extra time that is :) Thank you Anonymous!! Check out the finished blanket here.
