how to make a scab - this is an important step to take if you hurt yourself while making something or on something you made.
Step 1: Get Something to Hurt Yourself On!
I recommend getting a new bike with clipless pedals, but suit yourself. powertools would work well too.
Step 2: Get Hurt.
a scrape works best for maximum surface area. cuts are ok too. I discourage puncture wounds.
Step 3: Wait a While.
you should wait a while. some people recommend bandaids or ointment. I don't. you can use soap if you are dirty.
Step 4: Have a Scab.
you will grow a scab unless there is something wrong with you. if you don't you should see a doctor. don't pick at it.
