The main kit is really interesting as I've been able to use the self-coloured plastic without adding paint and it looks good. OK, some parts are supplied pre-painted but I'm very happy with the result.
After all that plastic, it's on to a card kit from LCut Creative for a signal box. A nice model and economically priced, perfect for the 4mm scale lineside.
Finally, soldering, or in this case desoldering.
Inspired by learning how to use solder wick, I've covered how you get solder off when it's in the wrong place. Dealing with mistakes is as much modelling and putting things together. Many people assume "experts" don't make mistakes. That's not true, it's just that they made then and learned how to fix things afterwards.
