Oh I'm sooo sorry!!! Where were the cuts... that might help us to give you some ideas on how to prevent injuries? Aaaannnd knock on wood.. I haven't had an injury in a couple of years.
So.... if I'm nervous, I take a deep breath, let it out slowly, repeat a couple more times. My music in my salon is some new age background soothing music. Never go down an ear with clippers. Always go from the leather out. Sometimes with small dogs I will use the clippers rather than scissor the edges. And ALWAYS know where that tongue is!!! If you can't get that muzzle shut.. just don't scissor until you can, and know that tongue is inside. Be very careful around tuck ups and armpits. If I'm scissoring a boy dog, I will hold the penis out of the way so I don't cut it. If I can't see something, I don't cut until I can or can feel something. Use your comb... a lot.
And never ever ever ever ever wipe your shears with a paper towel. That'll get ya about 8 stitches in a thumb lol.
There's always room for another rose in the garden.
