Don’t be intimidated by the number of pieces in a stained glass pattern. Instead look how complicated the pieces are.
You can have a pattern that has less than 15 pieces and is very complicated, as in this abstract pattern.
Or you can have a pattern that has over 100 pieces but is much easier to build.
Always keep growing and challenging yourself. How do you know you can’t do something without trying?
If you have only cut straight line patterns try waves. If you have done waves try curves.
There’s nothing like the feeling of accomplishing something you have never tried before.
