Until now I've generally gone with Duncan's method for painting diamonds on Harlequins, though I use the 005 Micron pens to draw the guides rather than using a brush. Nonetheless, this method is still a struggle, particularly when going for a consistent pattern. I looked online for stencils and if these work for $12 they seem like a steal, but I'm not necessarily convinced that they would be effective for things like a bent leg or some such. Can anyone vouch for their quality and if so can you enlighten me with techniques with them?
