Carrot log cabins: there's a learning curve

Inspired by yesterday's video about the adventures of a cupcake among the vegetables, I grabbed my smallest paring knife and decided to make my own carrot Lincoln Logs:

It's harder than I thought it would be.  I was having trouble getting the edges straight, and it was hard to cut deep enough without slicing off the end of the carrot.  Maybe an x-acto knife would work better.  I gave up pretty quickly and we ate the evidence with some hummus.
