It is really daunting for me as well. I am working on little baby quilts and using my walking foot for now. I can't speak to free motion since I don't feel I'm ready to practice that, yet. It helped me to slow down. Ripping out a bunch of rows because I didn't like the original thread color helped too - that showed me I didn't ruin it by starting over. I volunteered to make some mats to go under the mats used for our condo board meetings - mostly so I could practice. (Also because the old ones were awful looking).
Good luck!
