I've way less experience than you both, have never worked from raw fleece and the few attempts I made with a drop spindle were never going to be more than an exploration.
That said, when I started felting I did find and consciously use it as a part of my spiritual practice. Firstly in the creativity which is stepping into the making as a conscious choice and offering the best of my ability. Secondly in the surrender since once underway the actual result is beyond control, you bring it to a point and then start the rolling and all you can do is reshape at various points, the way it comes together in visual outcome is always unique and beautiful but not within your power to dictate precisely. That said, you put your all into it and trust the rest to be how it is meant to be. And for that I found myself drawn to chant, sing or otherwise make music - the rhythm of music assists the steadiness of pace hence the appeal of old waulking songs but also mantras, childhood rhymes, folk songs, whatever came into my head - inspiration or habit, who knows but for me it was important to make the craft part of my spiritual practice as I wanted every part of my life to have that context at the time.
Many of the items I made went to spiritual practitioners of one kind or another, so I wonder if they perceived my intention in some way or whether I just knew more folk in that world that wanted to support my efforts. Whatever the reason, I wove it that way intentionally and stopped at a point where the pressure of production for a deadline (Christmas gift posting as it happened) outweighed the joy of doing the work. I'm just restarting now about 15 months later, as I want it back to what it should have remained, a way of expressing creativity and spiritual practice, not a commercial product to be demanded and controlled by others, however supportive their intention.
