Have you heard of Leah Day of Day Style Designs yet? I found her blog called 365 Days of Free Motion Quilting Filler Designs and it's fantastic!
Every day she shares tutorials on how to do a different free motion design on a regular sit down sewing machine using great photos and videos. On the blog you can sign up for her free newsletter with updates on the quilting designs featured for that week.
This link on her website has a cornucopia of quilting articles and video demonstrations, and just her Frequently asked Questions page is worth the cost of admission :) Check it all out, it is well worth the time.
Enjoy the day!
