What is the best technique for getting the zebra print effect?

The best thing to do is "image" search zebra print - that way you get a visual of what the print looks like.
For me, I rolled out black fondant and then just took a sharp knife and started cutting in strips - the more stripes the better - layed out on the cake, fill in holes step back and keep going tell it looks good.

Good Luck - HTH
