I see lots of tips and "information" about spotting, but what I think I probably need is someone to demonstrate, then watch me try and offer feedback, "no, make the point of your brush smaller...pick up less dye...move it this way...that's right but do this more..." or whatever. A video might be the best thing we can have online and better than just written instruction. I normally do very well with written instructions but some things you just need to see, and motor skills you need to practice doing.
