|Dip pens and acrylic ink|
The other pen in the picture is made from bamboo and I've had it so long that for the life of me I cannot remember where I got it. I know I got it for use in life drawing classes after failing miserably to cut me own. (maybe I should give it another go...) The marks that it makes are a bold contrast to the other pen and as it doesn't hold much ink inbetween 'dips' there is a lovely variation in the ink even in one stroke.
My preferred ink is FW acrylic in sepia which I generally use very diluted reserving neat ink for only the odd mark within a drawing where a bit of punch is needed. The soft tone of the dilute ink lends itself to subtle washes of watercolour to my eye.
Pop over to Theresa's blog and see her beautiful work, the light that she captured in her last watercolour 'Winter Sunset' is gorgeous.
