My local hobby shop (Power Hobbies) called to say the plastic sheets I'd ordered last week, had come in. I now have 10 sheets of 0.25mm, 10 of 0.5mm and one of the thicker 2mm (all approx. A4 size), so I can go ahead and create the fuselage, in theory.
Damn meerkats have hogged my time recently, on top of my studies, but I'm determined to break this gear issue and make some progress. A friend said they've given up worrying over progress of their projects but I can't help beating myself up over how long it takes me to get anything done.
