Okay this is said with love..... <3
Why do you care what others think? People who quilt for charities have big hearts and can't possibly be "less than". If you feel unappreciated and looked-down on, maybe take your lovely self to another charity that will appreciate your work.
If you want to practice free motion, get some inexpensive muslin, or use scraps or old sheets, and make quilts for your local Humane Society. Dogs don't care what the quilting looks like.
As long as YOU'RE happy with your quilting skills, that's all that matters, IMHO.
