Thanks for all the comments guys. Please feel free to copy the "jersey barriers". I was determined to make some from existing molds, as a few had requested a mold, in the mold requests section. The pieces I used come from the Roman Temple, Station Builder, Machinery Builder and Lab Floor Molds.

@ dad1946 - I used masking tape to keep the lines even. I painted the area yellow first, stuck the tape on at an angle and painted black over the yellow. The paint bled through in a few places but a little touch up resolved that.

@ macattack - yes I am an Infinity fan, though sadly I haven't played in almost two years =( Really need to update my Yu Jing force.
