The tutorial is in German, but that is what she does in short:
- Stamp on fabric, best on smooth fabric on a rigid board.
- Heat set the colour by ironing the stamped fabric.
- To stabilize use iron-on backing or sew a zig-zag around.
- Cut the stamp close to it’s rim with good scissors (it’s called ‘narrow edged’ I think).
Great, isn’t it?
