Thanks for all your kind replies. Now to answer a few questions............
key4unc, I quilted them with black thread, filled the larger solid areas with pen and shaded a bit with pencil.
QuiltnNan, they didn't really take that long, looking and thinking where and what to stitch next took longest.
Diane007, it's not that hard, give it a go
Ifstamper, I drew rough guidelines on the fabric with air fading pen, then winged it.
