You can also take the free motion pattern and trace it over and over on paper. You can doodle on any scrap. This will fix in your mind the way the stitching goes, the size of the pattern - like making all loops the same size and the same space. I used up the back sides of computer print outs this AM while printing a calendar.
It will be easier to visualize on the machine.
I tend to size things smaller and smaller, so learning to size things consistently helps.
