On my travels to various comic shops last week I also snuck into Games Workshop, or Warhammer as the store on Tottenham Court Road, London is now known. I only popped in to grab a new pot of black and white paint but came out with a couple of pots more.
The staff were very friendly and helpful and they talked me through the new range of textured paints that GW have recently (a year or two back?) introduced.
I talked myself into buying one each of the texture paints as well as an applicator tool - yeah, I know GW's own tooling stuff is expensive and cheaper alternatives can be found but I got caught up in the moment.
Hopefully I will get round to using these soon. I will post some details as and when.
