I know how you must feel hurt for your aunt. Did the kids know you were upset when you left? Diane had a point. Your son may not have even known it was put in the garage sale.
Because we put so much love and time into our quilts, needlepoint, cross stitch, etc., I always feel so sad when I'm at a resale shop or Goodwill type of place and there is anything homemade with a price tag of a couple dollars. I think of the woman or man who made it and feel so sad. Sometimes I buy things I can't use just because I feel sentimental for the person who made it. Nutso!
