Machine quilting

Yesterday I decided to quilt the latest flannel quilt that I finished in August. Click on the link and scroll down past the journal covers to see the whole top. I call this curvy crosshatching. The top had been in pieces in a box for several years with just one day needed to sew it together. Does that mean I should put on a label that it took me over 10 years to make it, LOL?

Here is the back of the quilt.
Today I have another finishing class to teach. One of my students pulled out a project from a class in 2001 to finish. I hope my brain will recall how to do it once I see my handout sheet that she has with it. I only taught the class 2 times so it isn't an instant recall thing.
