These three skirts were made using the same basic technique.
This is the type of material I use.
The little finger is the perfect size for a form fitting beta skirt.
Mount the finger tip for painting.
I use a jumbo sharpie  it is just the right size.
There is no need for primer.  Acyrlic craft paint adheres very well.
Once the paint is dry, trim to desired length.
Trim a small to fit the waist of the  beta b-nut.
Now glue in place trim and decorate to your liking.
