As someone who does not have an in-depth understanding of proper execution of various styles (I'm still VERY new to pointed pen calligraphy!) I would like to humbly offer that a major part of my own personal enjoyment of calligraphy comes from knowing that I can EXPERIMENT without rules. I love trying different shapes and lettering styles, nibs, papers, inks, metallics... without too much pressure that I "MUST" proceed in a certain order. This is part of why I really enjoy creating it. This may also stem from my artistic background, a general rebellious attitude about "just doing it myself", and the belief that "trying it" is a great method for overcoming fear!
I totally understand that through my less than proper process I have a REALLYYYYYYY long way to go in continuing to explore the discipline, proper forms, strokes, stylings... and it definitely does not diminish my curiosity about (or appreciation for) learning the proper methods! I just know, for me personally: locked into a rigidity of only proceeding in certain steps would NOT keep me AS motivated as a "break the rules" mentality of experimentation. Just wanted to offer my two cents on a beginner's perspective...
The masterful and experienced artists here on the forum keep me motivated & inspired, as well! Thank you for sharing your beautiful skills.
