Wow and double Wow! OMGoodness you were so blessed. Did the seller tell you why she was getting rid of her quilting supplies? It makes me wonder if it was an estate sale and the family members had no idea of what quilting notions cost? Doesn't really matter, of course, they were happy with the sale and you were no doubt dancing all the way to the car!
Many people who aren't familiar with quilting think of quilts as just another blanket.
