Two blog readers shared some practical ideas on tools to guide lines painted
De Nick Freeman :.
"You refer in your post Berkey different methods of achieving the straight lines / edges in the paint, always a challenge. I found that commercial bridges are too low to the surface or too heavy. Necessity I came with a simple, inexpensive There are years that aid was effective.
"No doubt you have received other / better solutions but I wanted to share mine.
"The materials are: 18" rule wooden board with metal handle of a ARTTEC sanding pad, 3 5/8 "dowels (Hobby Lobby or such) and wood glue After having cut the grip pad in half and add affix ankles as shown in. Fig. 2. the pole ensures stability with minimal contact with the surface of the painting. ankles provide sufficient height away from the surface of the paint so that the brush ferrule can be pressed against the edge of the ruler.
"since the available pictures show, the implementation has been in use for a long time and was d a great help. Hope to see more ideas for you and your readers.
Sincerely,
Nick Freeman "

After seeing the post about John Berkey, Mario Zara suggested another tool to guide the painted lines.
"in fact, I really do not know what name I would give this tool (in English or in Italian!), but I can give you more information. The tool is mentioned in the book (I bought in digital form) Gouache for Illustration
(page 33), where it is called "Holbein RGB" (see the attached image): 
"Holbein the RGB may look like another gadget doomed to gather dust, but it is not. RGB kit consists of a plastic ruler with a groove and a glass rod with a point ball rolls perfectly into the groove.
"with it, you can draw not only perfectly straight lines with a brush, but also precise curves. For the straights, you hold your brush along the glass rod in just the same way you hold chopsticks. You hold the brush well away from the rounded tip of the glass rod as it rises in the fluted rule.
"When RGB is really in its own drawing is precise curves with a brush. The stem and the brush follow the edge of a French curve as easily as a rule. The glass rod is also a wonderful tool for burnishing marks left cut into the surface of a support by overzealous cutting a chilly. RGB is a small smooth tool.
"the tool is commonly used in Japanese animation studios. See for example here (search 'rule'): "
