The Sycamore, aka Buttonwood, produces huge and beautiful leaves. I've had one lying about for months just because I like it so much...never thinking that I'd be trying to draw it. All I have at this time is the initial layout with a very light 2H touch.
I've been working mostly with Stonehenge Vellum 8x10 and I had to jump up to 11x14 for this one. I have some Strathmore 400 Drawing and Canson Classic Cream Drawing coming in, all 11x14. Oh, and along with that, is coming a Speedball ink pen kit with various nibs and some Higgins ink. I have a RapidoSketch and a Rotring but I'm really interested in pens that can, with practice, produce variable width lines. Ah, the toys... :-)
