Now I have to figure out how to grid 14 to the inch... the wife has
cabin fever because of restricted movement due to her fall, and has
decided to do some needlepoint on 14 to the inch fabric :-)

Remember the old way?

Draw your 1" grid lines on a piece of paper, then lay a scale between
two of them, slanted, so that 0" is on line and 1-3/4" on the other.

Then place dots on the paper at the 1/8" graduation points on the scale,
and the 1" space will be divided into 14 equal increments.

Repeat as required to make sure you get parallel lines in both planes
and then Voila! Once you've drawn lines through the proper points,
you've got a 14 X 14 lines to the inch grid.

Well, not _quite_ Voila!, but it'll get you there in a low-tech way, :-)

I _can_ draw :-) My problem is to merge a picture onto a grid.

Ahhh... I see.

The way I do it, in AutoCAD, is to generate the grid, assign it to one
layer, and then insert the picture on another layer and scale it for the
best fit on the grid.

maybe you've got a graphics package that'll allow you to do something
similar?

Print grid on paper. Put printed grid paper into printer. Print picture.
No big graphic package needed that I can see.

If you use a graphics package to generate the printed grid, then you'll
need some way to scan the picture and scale it so that it'll print on
top of the grid correctly, which might be as simple as telling your
printer to scale the scan up or down to fit on an (say) "A" size sheet.

When you place borders on the cells, and arrange them by pixels, you
can make a square grid, then define the print area, and then by margin
adjustment, and experimentation, you can make it print at the exact scale
you want/need it to be at. I do it, when I am making heat sink templates
for little Ghz RF amplifier modules. It allows me to make perfect
templates, then I can spec them on the drawing too, if one gets done.

Tricky part there is adjusting for margins.

Yep.

Another way could be as simple as putting the picture into the printer
and printing the grid on top of the picture, but you'd still have to
tell the printer how to scale the grid so everything would come out
right, so that's a "big graphics package" of sorts on both counts.

JF


Excel would even allow pasting the image on top of the grid, then
sinking it beneath it.
