First, I am so sorry for your loss. This has got to be really hard to deal with. My thoughts are that IF you have the time, energy and inclination, I would take the time to measure and mark the yardage with a specific price-----you will make a lot more money this way rather than selling by the pound or bag. You can fold and group all the FQs together with a sign that says $1.50 each (or whatever price you choose). Any scraps and odd size pieces can be put in quart or gallon zip lock bags and price with a sign. But if this is just too much for you, let the estate sale people do the work in setting it up---they generally get a hefty commission at 30-40%, so let them earn it.
