One of the best ways I know how to practice your new sewing skills is by sewing on a sewing maze. You can practice turning, sewing curves and getting the sewing machine to go where you want it to go.
I've taught MANY people how to sew in the last 20 years and I've always started them out sewing on a sewing maze like the one I sew on in the video below.
Take a few minutes to watch me do the sewing maze on the video, then download your own maze and practice sewing on it. I have included an Easy & a more Difficult version, depending on your skill level.
