As always happens, a genius - in this case Gregzgurl (Sue) - popped along a few posts later and figured out how to do it.
So since sometimes Beate leaves the place unlocked, I snuck in and did the tutorial today on just that - glowing lights. As Sue says, it's really pretty simple - just a dot of white gel pen and my pastels, which I've really been neglecting. They are perfect for this technique.
Wanna see a video on how to do it? Sure you do - you're off today right? If not, just watch it at work. :).
