Cake is so lovely.  How do you do the lace wrap?

Thank you.  I actually learned the technique via the internet.  I used a #2 tip and piped the melted chocolate onto parchment.  I let is set for about 10 minutes in the refrigerator so it partially set but was still pliable and then I wrapped it on the cake.  Back in the fridge for another 30 minutes or so and then peeled the parchment off.  I think a smaller tip would've given me a cleaner result (next time).
