I am so sorry she said that to you I am sure you felt like she stabed you in the heart. I also crochet and when my grandma was alive she made every grandchild a crocket bedspread. I decided to carry on the tradition. When my cousin was engaged I was in the middle of making her a crochet bedspread as her wedding gift, now let me say yarns is expensive too. My sister saw it and said WHY would you give her something that CHEAP??????? I just about cried. I replied if I made minimum wage for time I put into it, it would have cost me about 100 times more then what you are giving her as a gift. When I gave it to may cousin she cried, she knew I was carring on granny's tradition.
Try not to let clueless people bother you, I know that is easier said then done.
