Sketching stylus for ipad from ready-made materials

We were experimenting with various ready-made materials to create a stylus for a continous sketching experience. We wanted the stylus,
1. to support changing wrist angles in smooth sketching (rather than only 45-90 degree holding position) and rendering
2. to offer a sustainable alternative to head part of existing high end styluses like wacom bamboo and alupen
3. to have a real-pen-like weight balance for better sketching experience

Step 1: Material and tools

To build this stylus you need:

- metal knob (from ikea house or similar)
- a bolt and some nut (all same thread size with knob)
- a piece of textile (any textile that works when using between your pad and your finger)
- a rubber band

For retro cover: 
- a Rotring (or similar) mechanical pencil (broken ones are preferrable) 

Tools:
- a craft knife (for cutting the rero-cover, for cutting the piece of textile you might also prefer a scissors)
