Jason and all,

I love that stuff!

Big sheets can be found at Rainbow Symphony (from whom I bought some
colorfully-framed, silver-dollar-sized "diffraction grating peepholes" to
great delight of visitors).  Their URL is rainbowsymphony.com.

Ten 6"x12" sheets can be had for $2.50:

Lovin' the rainbows,
Summer

I'm looking for a good source for diffraction grating film.
Edmund, Carolina and Arbor Sci carry only little sheets.  Web searches only
dig up manufacturers of precision and custom diffraction gratings for
specific optical applications in technical industries.
I just want a run-of-the-mill (?) diffraction grating.  I could use a
12 inch by 36 inch piece, and then some.

Thank you in advance,
Jason
