    Another project for SWMBO...

    Need to paint (?) a grid on a white board in some fashion that will
    hold up to some (Girl Scout) abuse....

    Magnetic object to be placed inside the grid.

    Paint (?) or some other grid construction suggestions?

  2. I used to use automotive pin striping tape to make schedule boards.
    BTW, a coat of good automotive paste wax will seal the board's surface,
    and keep dry markers from leaving stains that require Windex, or other
    strong cleaners.

    My favorite was "Turtle Wax Hard Shell Paste Wax". Its a good things
    them suckers are so slow. You can usually apply to or three good coats
    before they get away from you.

    prove it.

    tape ? (painter's or electrical)

    Brainstorming ideas:
    (Including some wild ones..)
    1)Layout a grid using graphics grade vinyl tape
    (not the electrical tape with a gooey adhesive)
    2) Stencil and spray paint
    3) Use permanent marker to make grid
    4) Score the grid and fill the scratch with paint
    5) Have the white board laser engraved or CNC machined
    6) Glue string on the board
    7) Melt a grid with a soldering pen
    8) Silkscreen a grid and use epoxy paint
    9) Project a grid from a digital projector
    10) Cut up the white board into tiles. Gap is the grid.

    Excellent idea, Michael! THANKS!

  6. I did a 4' * 8' board by laying out the endpoints on the edges of the
    board. Then I let about two inches of tape hang over and had someone
    hold that end in place with their finger while I peeled the backing and
    kept a gentle tension to position the other end. It was gently lowered
    to the surface, keeping it tight. After making sure it was straight, I
    wrapped about two inches of the tape around the edge, and onto the
    back. There are small rubber rollers made to burnish it into the

    After I got started I had about 45 taped lines on the board, in under
    an hour. Then it was time to wax it.

    You might have to go to JC Whitney to find the colors you want.

    Virtually impossible with paint (won't stick to Porcelain used to coat
    the metal white boards.) Ever considered some tape?

    Sounds silly to me.

    Give them the pens that go with the whiteboard so they can draw the lines
    back on it.

    Ask nicely and they might tell you how to use scissors to cut the right
    shape of felt to stick on your magnet so it doesn't scratch the board.

    Crap....... You might get someone telling you how to stick drawing pins
    around the edges and wrap string around them to set up your grid.

    Then you'll get lessons in how to make bobbles for your bobble hat.

    The possibilities are endless.

    And what would you know of SWMBO ?:)

    It's some sort of message that cannot be transmitted in plain text?

    You take a piece of cardboard and cut two circles out of it and cut circles
    in the middle of them.

    Then you put them together and get some wool and thread it through them lots
    of times in a cicular way.

    Then you cut around the edges and tie stuff together through the middle and
    pull the cardboard off and fluff things up.

    Then you have a bobble for your hat.

    If you know about No1 needles and go a loose six ply you can knit a Doctor
    Who scarf in a day.... and put tassles on the ends.

    If you use drawing pins (bugger, thumb tacks) and wool you can do the curve
    out of straight lines.

    If you get hold of a proper wooden cotton reel and stick some nails in it
    and get hold of a crochet needle you can make long tubey things as well.

    Since I have got older I assume they use them for Rasta Hats if you get the
    colours right.

    What about an indelible marker for the grid lines.

    Oh bum, perhaps I have fallen foul of SWSMNBR.

    Fortunately I don't have one. Sometimes life is good.

    Rumpole of the Bailey used it quite a bit IIRC.

    Got one more:
    11) Laser print a grid on paper and stick sheets on the white board..
    Use as many sheets as necessary. Magnetic pieces should still stick.

    As shows up, it is not so much how you apply the grid, but how you overcoat

    Yep. That was one of my all-time favorites on PBS.

    Black or other colour insulation tape? Easy to peel and replace if you
    need to and easy to clean up after if the board is to be re-purposed at
    any point.

    I have found dry-erase marker ink will dissolve marks made with
    permanent markers (Sharpie markers, don't know about other brands).

    One poster talked about a wax coating on automotive pin stripe tape.
    The same could be done after a grid is made with a permanent marker.
    Or instead...maybe a urethane coating might work.
