I read a wonderful article by Leah Day who quilts with her feed dogs up. This is interesting to me because I have so much trouble with free motion and having my feed dogs down. I am going to try this and report my progress back to you'll. Here is the link for her article http://www.leahday.com/art-dropfeeddogs/
If you free motion with your feed dogs up, please let me know if you like it better than with the feed dogs down.
