Haha. I had two novice clippers over a few weeks ago to practice on a heifer I needed to slick. We did the normal clip job, but then I drew them lines down her sides and let them practice blending them out. Unfortunately, I had only one pair of blending heads, so someone had to use the blocking blade.....looked somewhat like this but slightly more spots....my mom walks out the house the next morning, looks out into the pasture, and informs me that "Pixie" has ringworm and I need to treat it ASAP!!! LOL
