It has been a while since I posted anything but this is worth breaking the silence.
Sharpies are awesome. No doubt.
However --- At a recent design charrette, Mike Taylor, AIA of DP3 Architects in Greenville whipped out the largest marker I had ever seen -- the Sharpie Magnum. I was impressed and a little envious -- a typical male response. So, after the charrette I ordered a few for myself.
They are great markers -- if you remember to use them in a well-ventilated space. They are strong in the odor department.
They lay down a thick, very opaque line and have a huge ink reservoir. This is the pen for bold lines and bold ideas.
Draw big !!
