Parents should not outlive their children and I'm so sorry you are having to handle this part of your daughter's estate. My heart aches for you.
I want to encourage you, if you have the time, stamina, and facility to hold a quilting sale separate from the estate sale, to do so. I have done this twice in the past 8 years, with my own stash preceding a move, charging $3 per yard - measured and cut at the sale - and have made over $1100 both times just by opening it to local guild members. I have never had a stash that filled a whole house either!!!
It's a good idea to have helpers to measure, cut, and to be eyes on the crowd. I took appointments at my own sale so I was not overwhelmed. You likely would make enough $$ to take them out to dinner afterwards with no problem, too.
I cut any thing from 1/4 yard to 2.5 yards, but sold fat quarters only if they had already been cut. To keep track of what each buyer was getting, I made slips of paper like below to send to the 'cashier'. It was a huge help to just mark a 'chit' in the correct space after each cut.
Best to you in this endeavor. Wish I could come help.
