The fact that you stated that you make lap quilts for the nursing home...and you found this wonderful estate sale. I don't think it was any coincidence that you got such a great deal on fabrics!
I would imagine the person that had filled those totes with fabric would be so happy that what they left behind is going to such a wonderful purpose. Bright colorful quilts to brighten someone's days....you're thread about your great find, just makes my day!
