Argh... I have never done any kind of felting, so I am no help. I only can support you by observing, that you always choose/make (in my opinion) beautiful color combinations indifferent if you knit, dye or felt. But I have no idea how differently wool behaves while felting… I hope your ideas work out to your satisfaction.
Thanks @neumannsalva! I have one almost done. The second will be easier because I’ve already committed to colors and design. Having a deadline makes it less fun. That’s probably true for everything though.
