Awesome!! I am sure someone will snatch that right up. :) You are doing great for only being 6 completed quilts in, I think you have a long quilting life ahead of you!!
A good idea for practicing free motion is to make a larger sample that is just two whole pieces of fabric with batting between, free motion it, then cut it up into smaller bits, bind them and donate them to your local animal shelter for crate quilts. The cats don't care what they look like and you get good practice!! :) Plus working with a larger quilt is better for practice as maneuvering the quilt under your needle is a lot of the process, and a small piece like a pot holder doesn't give you that.
Cheers!
