Does Hobby Lobby or Michael's carry this or is it online only? I want to find an economical source for it if possible.

I've gotten it at an art supply store.

loast piece i picked up was at hobby lobby in the fabric dept. they have it with their quilting supplies

If you need it to cut into strips for cake wraps, they're available already cut here:

Thanks! I will check those out

I ended up finding it at Hobby Lobby in the drafting department, most of the staff told me they did not have it - must be easier than looking it up for a customer...
I want to try wrapping a cake in chocolate
And trying the faux bois technique...

Do you think it is like other things, where there is a food-safe option and a non-food-safe option?

The acetate I use for caking I bought at a cake supply place on the Internet. I did have some art-supply acetate already, but did not use that because I assumed it was not food safe.

I guess I don't really know the answer to that - I assumed acetate is the same product in any application. I did a quick google search and didn't find anything on it.
