I started on muslin and then moved on to dog quilts. My dogs are not critical of my work and love my mistakes. Muslin is cheap to work with and you might find a use for your creations. They work great for placing between your cookware and nice dishes to keep from scratching/breaking them. Hang in there, it comes to you. I watched a lot of You Tube at first. And relax. My first designs were so close together I lost the quilting effect, just squashed all the batting flat.
You will get it. Don't worry, be happy.
