I am planning on making a Dr. Seuss cake at the end of the month and I'm wondering if anyone has any tips on how to get those black lines on the fondant pieces to make it look like cartoon drawing, or wrinkle lines in the hat.

I'm guessing people used edible markers but I never seem to have luck with them (at least the Wilton brand). Does anyone have a brand that they recommend? Or is there a better way to do this? (black piping gel hand painted on?)

Thanks for your help!

I have and use the KopyKake food markers. They have two different tip sizes on them (one on each end). I got mine on Amazon...

For lines like that I use Black Food coloring with a little vodka or clear extract. They come out much darker and more consistant.

Thanks for your help! I bought the Kopy Kat pens and they worked great! I also used the food coloring/vodka tip for another cake (hand "painting" leopard print)

Thanks again for your help!

I used a thin brush and airbrush color...straight...no dilution. Changed up the brush thickness for the details on the coordinating cookies. A wide brush, snipped and thinned a bit worked well for those areas with more 'shading'.
