Drawn with a Sailor/Wancher Turquoise 1911L. The M nib on this pen comes to a sharp point which allows for some line variation not from flex but based on how deep the firm nib digs into the watercolor paper. The Noodlers Black ink is a little dry and that contributes to this effect.
Sewing paper is lots of fun. Taking a lot of my cats and sewing them to pretty paper. Not sure what I will do with them after that, but they are fun to make.
