Where can I buy long narrow paper to make menus?

I am making one for each plate (each guest). I want that long, narrow paper that looks like a rectangle. Where can I buy about 250 sheets?

TIA

i did regular 8.5x11 paper, but cut it down the middle...



i used watercolor paper, which can be purchased at any art store, but you can also get paper at staples, office max etc...

paper presentation has a nice selection. and since you want it narrow, i would buy a paper cutter, preferrably with a rotary feature and cut it to size yourself.

paper presentation is in the city located near FIT. just search for it online.
