I needed to do some touch-up on a picture I am doing but I didn’t have a paintbrush. Then an idea came to me. I had some felt pens which had dried up, so I got my tweezers and poked around until the white seal at the top of the pen came out. I disregarded the inner cloth and put the pen in boiling water for a few minutes until the pen-nib was white in colour and left it to dry. The pen is now great for painting and each pen-casing has its own colour so each paint colour can have its own pen.
