Sleeves of molten mag-ma

I fear that there is no escaping - this will be the volcano dress forever more. It certainly doesn't help that it's brown wool, and the sleeves are lined with pumpkin orange.

I finished the slashing on the first sleeve, and have taken some photos along the way. The first step is to mark out the position of the slashes. Then sew a rectangle of fabric to the right side (fashion fabric side) in a very thin channel, similar to a button hole, but straight stitch rather than zig-zag. There should be enough fabric to turn to the other side and then fold the raw edges under.
