There was a time when I would have been really upset, just like you...you put so much of your time and work and love into these handmade things, and it is heartbreaking to see them taken so carelessly.
My sister treats things this way and for years I refused to give her anything handmade after I saw her one day raking ashes out of her fireplace with an oil painting I had done for her.
But I have changed my mind about this. My sister and I are old now and the only ones left alive of our family. I can and will make many more quilts, oil paintings, leatherwork, etc.....BUT I CAN NEVER, NEVER MAKE A SISTER. I will give her tons of quilts and she can wash her truck with them if she chooses...because I love her so much, that's perfectly okay with me.
