[OT] Draw straight lines (With a pen/pencil)

["Rob Mouser" <groups@xxxxxxxxxxxx>]

Sorry for the OT but something tells me that this group with its
fountain of knowledge might know the answer!

I looking for a 'tool/gadget/thingy' that I have no idea what the name
is, so the only thing I can do is describe it!



Basically it's a sheet of plastic that you place under a sheet of paper
to aid drawing straight lines. The sheet has hundreds/thousands of tiny
bumps which are just big enough to guide the pen/pencil in a straight
line.



Before you think I've lost the plot, it does exist (Or at least 'did')
as I used to have one that I have since lost.



I've tried a craft shop, John Lewis and a large WHSmiths with no joy,
just dazed expressions from the assistants :-). Googling is just too
vague!



Thanks



Rob
