I didn't mention it, but since some have.. both my aunt and uncle (married) were diagnosed with lung cancer this year within 6 mos or so of each other. My aunts was straight forward, but my uncle was misdiagnosed for a few months because the symptoms he was having had nothing to do with the lungs. They finally found it in his brain and and then the lung. Sometimes these things don't produce symptoms like you'd expect which may have been what happened to your mom.
When asking questions ALWAYS post the name and a link for the pattern if you have it.
Mason, my thoughts and prayers go out to your Mom and you, and the rest of your family. At a time like this there is not much one can say to help, except perhaps that I am here for you any time you need me! Drive safely my friend!!!
I love to give homemade gifts... which one of my kids do you want?
