Quilts are as different as MOTHERS> there are good ones and bad ones... some are sweet and colorful, some are dark and shady. You get what you get. I can tell you a truth. There are no quilt police, There is no right or wrong way. There is you and a bunch of fabric, and your creation when you are done. I am a Mother 6 times over, and if I acted like your mom I would exspect my kids to politely say "OK MOM, you do it your way and I will do it mine."
My heart hurts for you, but you need to get elephant skin or tell you mother the truth~
