I'm so sorry for your loss. My mom went to heaven 13 years ago and there are times that I still miss my best friend.
I'm glad that she splurged and enjoyed her new sewing machine! And now you have some wonderful pictures of your mom to cherish. May your sister enjoy her new machine. I'm sure that your mom is smiling down that she sees all of you sharing in her love of sewing.
((((Hugs))))
