I can easily see that she's crammed the room with all things sewing related. Lots of stuff can be put in those drawers. Come on, quilting is an expensive hobby. It's not hard to rack up a couple of thousand in notions, fabrics and what not. So selling it all for $500 seems reasonable to me, even if the fabric may not be in prints that you personally find appealing enough to purchase.
I hope she finds the right person to sell this to.
