15. Any mundane practices that are associated with this deity? Wayland appears to be a god who is happy to change with the times, at least according to my own UPG.
Obviously blacksmiths are quite a bit more rare nowadays. Still, if there is a forge, I’d feel it likely that Wayland is there. He will involve himself in just about any craft that involves heat and metal: soldering, jeweler, stained glass, auto mechanic, machinist…these are all vocations he would happily patronize. I have also felt his hand in woodworking and drafting/sacred geometry.
Where I tend not to invoke him as inspiration is for textile-related crafts. Brigantia answers much more readily for these.
