I had a project to do in school and instead of using a drip vector found via Google search, I decided to make my own. I have them up for free download at the bottom. Lets get real, drips and splatters are very 2006, however there is always that one project that someone ask for drips or splatters.

I basically just put a drop of ink on a sheet of paper..

Then, I hung it up on the cabinets to let it drip

I let them sit to dry after about 5 minutes. 

Last step, I scanned it, placed it in illustrator and image traced it.
