Just jump in and go for it!! My 12 year old son occasionally watches the Leah Day craftsy classes on my ipad with me and he chose the "circuit board" for his bed quilt that I'm working on. After a small practive block I decided to just go for it...
Sure, not every junction is exactly 90 degrees, not every stich in the ditch is exactly in the ditch, not every travel stitch is travelling the correct path, but there is sooo much that looks good and we (*I*) have to focus on what is right and that is 99% of it and my son LOVES it. I'm almost done completely, just some more quilting for borders and in the smaller squares.
