The tutorial is very easy to follow and its says the mat isn't the most prettiest thing but that it works....and yes it does! I sewed all day yesterday and my foot pedal did not move! I love it!
There's a lot of bulk under the machine and the matting is grippy so I did use a sheet of paper underneath to help feed it through, as the tutorial suggests. Its easy to remove once the binding is on because the paper perforates as you sew, just like paper piecing.
So in conclusion, its a fun project, its a great tutorial, the mat works perfectly and I'm a happy sewer :) If you're having "wandering foot pedal syndrome" like I was, then this non slip mat is a great solution.
