It has been months back ,but I bought at Hobby lobby and the Dollar store or Dollar Tree store and Party City ,too . It is there , just have to find it!! Where are you located?

I got mine from heirloomsbysharon.com also, great price, get the opal, it is more clear with hues of color through it.

I find it at the dollar tree, its the foil type wrap in the party iles. it is real shinny

Wrapping paper and gift card stores usually carry a fairly good selection, such as the Hallmark store or Greetings N More if you have anything like that around you. Beware though, that the colored stuff MAY bleed when it gets wet. Test a piece to see. The iridescent clear stuff won't give you that problem though. There are a few websites that sell it as well. I do not remember the name of the one that has so many varieties, but will post again if it comes to me.

type mylar in your search engine. You should be able to choose from there.
Hope it helps.

Party supply stores have this stuff too. Probably not as cheap as the dollar stores, though.
