Stencils with additional freestyle doodling.
You start with your black paper/card and use a stencil to draw around to make your basic design with a bold white pen, in this case a white uniball stylo. You then either shift the stencil a bit and draw again - or you can just draw freely.
These two are less 'busy'
Add any additional wording using freestyle writing:
They could be used on cards, tags, a hanging mobile or even as framed mini pictures.
Thanks for looking and for any comments,
See you tomorrow,
