Tight Squeeze First Stages

I saw this woman at an antique car show, juggling two little boys, twins I think, through two of the cars. The day was dun for me to take lots of photos, but the heat (105 degrees) was tough.
I decided to snap a quick photo and try this subject, which was a tedious one to some degree, with all the refelctions in the car.

So this stage shows the transfer of my own drawing onto velour paper. I have been (in the past) using carbon transfer paper, for this step.

I have however, found that using a sgraffito line, (pressure) into the velour paper, works better for me, way less messy. After the line is impressed into the paper, I reinforce with a pastel pencil, which fills the indent.
