While I continue to do one off solo games, I am getting lots of ideas for a mini-campaign from reading Donald Featherstone's Solo Wargaming book (available as an iBook). I remember reading as a library book last when I was 13 or 14 years old. I'll probably end up "mashing" up the campaign approach from KISS Rommel rules with the chance card ideas from Solo Wargaming.
In terms of current modelling projects, I have two on the go: building up my very small 40K Chaos force; and creating some units for a KISS Rommel game using some old Peter Laing 15mm models with home cast vehicles.
The home case models are originally made from balsa wood, covered liberally in PVA glue and sanded, before creating a latex mould for plaster casting. Its a bit hit and miss with the resulting models all which all need some remediation work, but I'm not looking for perfection and I get to create some hypothetical forces for next to nothing. FINALLY I get use up some old figures I'd packed away and carried halfway around the world.
