Sharpie Pen "Tool"

This picture could have been included on the last post.

A handy tool to have is a Sharpie pen. This the old style, wide tip permanent laundry marker.

The back white end of the Sharpie is a great burnishing tool.

Here I'm smoothing over the paper when covering the balsa fins.

Just be sure the white barrel is clean. Any dirt will transfer to the white paper.
