So sorry for you loss of your sister. I lost mine a couple of years ago and my bil has not done anything with her things yet. She was a designer and had loads and loads of supplies, fabrics, trims, buttons, notions, etc. He is well aware of the value of items as he totally supported her in her. What is sad is that I heard thru a mutual aquaintance that he would rather sell her items than offer them to his family or friends as he does not want to be reminded of her when he sees anyone who might have her things. I understand that to a point but I would like to have some momentos.
On topic of the thread, I've told my hubby to ask one of my quilting friends about value of my things prior to selling/getting rid of my things. He is not sentimental in those ways so I'm sure my stuff will find new homes in one way or another. He knows the value of my machines so that is a good thing--I don't expect that he will just give to goodwill at least.
