WOW! Another voice to the chorus of "glad you're mostly OK".
I do cast while sitting down, but I wear a full face shield, a hat, welding gloves, an old thick leather jacket with a high neck, denim jeans with thick long-johns underneath (my casting is typically done during winter), and some good, thick leather hiking boots.
Someone who goes by "L. C. Clower" on YouTube posted on my YouTube channel (sfliberal) about this thread, and thanks go out to him. That could've been really nasty. As a result, I will be buying a good, thick apron for use during casting sessions.
The Tinsel Fairy did come to visit me one time (yes, I had to learn). Splattered all over the front of me--face mask, leather jacket, etc. Thank goodness I had my stuff on, because I walked away from it totally unscathed, but plenty wiser. Yes, a full face shield *does* provide eye protection; I know this from experience.
