Done with dip pen and black Talens Indian ink. The dip pen is very old, 1967, I used it at school when I was 10. The next year we started to use fountain pens. Only the nib I used was ofcourse new.
Abstract Ink doodle and background on Yupo paper, using pinks, purples and blues. Apparently this year's colour is Ultraviolet! Design available as stickers, clothing, prints and decor.
