There's no model making voodoo .But thank you anyway,card is very fast and once you know what it'll do when you use the evil glue,and more importantly what it won't . Then it's just about shapes,(ciicles will alway be a killer as were wired to see a perfect circle so any deviation is instantly noticeable ) the key is new blades ,ALWAYS use new blades the second you use an older blade (guilty of not tacking mine own advice ) you get dragging and a torn rough edge.
I took a break from the paid work and found a solution that means I can mark this as CBa'd and it still be of some future use.Also I've painted that much red lately that I've used a 3/4 of a bottle of Miniature Paints Bright Red,and a full bottle of Game colour red ink.
