So sorry to hear of your Mother's passing. You are in my thougths and prayers.
Hold on to them, as you will treasure them as time passes. I have some of Mama's that she made years ago.
She had lots more and my sister or some of her family broke into Mama's house and stole all of them while Mama was in the nursing home. They probably sold them all.
Your sister was so kind to offer them to you.
It makes me feel closer to Mama with her things.
