You can see I had to snap some perpendicular lines first to make sure it's on straight...then 'pounced' the pattern on (chalk powder bag, banging against perforated holes of pattern).  

Meanwhile the chalk powder also falls into my mouth and on my glasses.  Then I painted-in most of the line work.  I tape the pattern up to refer to, as it's hard to see the lines sometimes.  

My husband Dan helped me to move the ladders & plank around, then played some nice guitar music while I painted, as you can see in the background.
