You are so very fortunate!!! I would have done the same thing!!! You have alot of work still ahead of you but its great bonding time with your mom which is fab!! Remember if you want to you can always post some of the fabric here
I would be more than happy to help you sort through it all - you could pay me in fabric lol
Maybe you could make a quilt or two for your church or make some to donate for linus !!!
Great job!!!
