I have to paint a wavy line 5ft thick on a wall any suggestions on how to be consistent on the wavy line?

Mark two lines equidistant down your wall, with their distance apart equal to the depth of your waves. Get a 5+ foot length of board or molding that will not excessively bow, and mark the center of your board. Drill two holes and insert pencils in each end, 5 feet apart. Standing in the center and holding the board with both hands outstretched as far as you comfortably can, ';draw'; the board down, making your wavy lines, making sure the center of your board uniformly passes over (but not past) your wall line as you make the waves. They will be consistent in width and form.

Use a level ,72 '; one, or a shorter one and a yard stick. Then measure the same distance between lines.I have to paint a wavy line 5ft thick on a wall any suggestions on how to be consistent on the wavy line?
Mount a skateboard truck at the center of a five foot long piece of 1X4 close to one edge with the axel parallel to the length of the stick. On each end and on the opposite edge mount some sort of markers. Perhaps you could get lumber crayons (keels) from a local building supply. With the truck at the leading edge and the stick held verticaly, draw the markers gently along guiding them either by the lower OR the upper edge of the proposed wave being careful to maintain the stick in a verticle position and watching the markers for wear and contact with the surface..
Cut a 5' piece of wood and attach a piece of chalk on each end. Paint will cover the chalk with no adhesion problems.
You need a straight line 1st. Then cut out a large circle from a large cardboard refrigerator box. By centering the circle on the line you will get a consistent wavy line. Mark the center of the circle on the edges so you can get it right every time. Another way to do it is with a projector if you have access to one.


Have fun with your project!
With a pencil draw a single line in the patten you want, roughly the center of what will be your wavy line. Use a yard stick to measure 2 1/2 feet from each side of the line every few inches, marking with a small dash. Do this on the upper and lower side. After you complete the stencil, free hand the wave with your pencil, following your dashes. You will have your wavy line :D I hope this helps!
