Sit back and relax with this Zen Blocks Free Motion Design. Believe it or not, this is one of the easiest free motion quilting tutorials out there. The circles on this pebble design don't have to be perfect, so you can overlap your stitches, and the design will still look great. Try this free motion design on your next DIY bath mat for a spa-inspired look. The slate grey color in this DIY tutorial would look great for any bathroom. Feel free to change up the colors if you want to get a more cheerful vibe. We love this design no matter what.
