That was very nice of you to apologize and i hope whomever you hurt will feel better about the situation. I'm not sure about what's going on but i just wanted to tell you that i'm sure it happens to all of us. Most of us have the same places to choose our fabrics from, we are bound to have similar or the same fabrics from time to time unintentionally. Also it seems to me that there would be very few ways to tie an appropriate knot for a blanket
But i'm really not sure...
Good luck with the situation.
