Thread Fusion

I am to give the demonstration for the longarm meeting for the month of May.  I watched the Thread Fusion 1 video by Jamie Wallen.  I thought I would try to do some of the thread fun from that video for my presentation.
This is my first practice piece:

It seems to me that thread fusion is an exercise in positive and negative space.  You make your design and then echo your design.  You can fill in at that level.  Or you can echo again and fill in that echo round.
I also have a lot of old jeans so I thought I could use those jean legs as part of my demo canvas.  I was concerned that I would have trouble machine quilting on denim and over the denim seams.  It was fine.  I think if there were 4 seams meeting in one spot, I would have trouble.  Two pieces of denim meeting together was fine to stitch over.
Here is the back of the practice piece:

I was just using leftover bobbins so the back is quite motley.  But it looks cool too.
