Many thanks for your comments. My experience with 6mm initially was total despair having bought this large amount of units. However, once I got started I got hooked. For whatever it is worth I had a go at a high-level painting guide on my blog last year.
I try to find the resting place of the Colour Sergeant this weekend and report back on my blog.
Come by and say hello at Salute (Kalisz 1706) or Joy of Six (Lesnaya 1708) if you are around.
Good gaming for you too,
