You are wonderful! The teacher is going to love the quilt and the reason you are giving it is precious. My youngest daughter is left handed and when she was in kindergarten the teacher made her grab the back of her chair with her left hand and forced her to use her right hand and to write right handed. I was furious and in no certain terms she was told never to do it again and she did not. Of course that situation was not even close to what your little one went through and I am so thankful for that teacher after reading your story. Teahcers are such an important part of a child's life and can make or break a child's desire to learn.
The teacher is going to love your lovely quilt and all the effort that went into it to make it your best. Thank you for taking the time to say thank you to her. My youngest daughter is now a teacher herself and a very good one. Blessings to you.
