I got my first client for logo design and they asked for a custom watercolor illustration of Iris flower. So I researched about iris flower and did a rough sketch. From there, I started rendering color using a special brush from GrutBrushes.
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.
