You may create and use an Artbrush:
1) Create a shape that corresponds to the desired shape when the path is straight,
2) Drag the shape upon the New Brush button and choose New Artbrush,
3) Apply the brush to an open path with the earring hoop, or to a closed path starting/ending at the top.
I actually did that earlier and it worked when I made a straight line and applied it ;-)
The one glitch however, is what if I want to change the taper amount...maybe make the top thinner or the bottom thicker...That was my only issue doing it that way, was not being able to control the thickness..any thoughts?
thanks so much!!
You may adjust the original taper and Alt/Option Drag it upon the Artbrush to change it; when agreeing to Apply to Strokes, you will get the change in your earring.
You are welcome, babs.
