Study in capsicum ...
After experimenting with many tools for quick sketching with pen & ink I have settled on the Bic Biro finepoint. The tool is so responsive & sensitive it's almost like a pencil. To qualify, I hold no shares in the Bic Biro Pen Company.
These quick capsicum studies are the basis for a painting.
Yes the biro is quite slimline. You could use one of those slip on spongy pen grips. I don't know what they are called. There was a time you could buy this Bic Biro pretty well anywhere, even in the supermarket.
Horses for courses really, let me know if you love or hate them.
Peter Cusack's drawings in Danny Gregory's "An Illustrated Life" are all done with the cheapest ballpoint pens he could find too. I've seen the ballpoint used to do an excellent copperplate letter form too, with varying pressure one can get some surprising results.
Thanks for your comment.
