I agree, I think the plastic paper with grids would be terrific!!

Li works for APH. So, I think he was asking if there was any interest in having the Draftsman film come in a gridded format. The film is not expensive if your student is eligible for federal quota money. Li, would it be possible to get the Draftsman film in gridded format?

Li,

Forget the plastic film.  It does not come with gridlines, and the plastic is expensive.

Use plain paper.

If the plastic films/paper used with Draftsman come in with raised grid lines, with that help?

Thanks,

Li
