I make my Zebra beads WITHOUT using clear on both sides of the lolly! First importance is to make the twists TIGHT on your twisty. Next, put a small layer of CLEAR down on your mandrel, then apply your twisty by PUSHING it onto the clear base, don't let it stretch when applying it. IF I used, for instance, a White base, then stacked Transparent DARK colors, you'd see a pleat instead of the black stripes! (Oh and you'd probably not want to make the clear coat as thick as I have)!
