Just a note...Starbucks has 3 bags (pastry) of this type that are being used (at least here in the Bay Area)as of this writing (Dec. 2015).
One....the actual bag in the video.
Two...a brown bag similar to the original, but slightly different in size and décor.
Three...a larger, white bag used for "hot" treats (reference: La Boulange "caution: very hot" warning on the bag)that I was given last week when asking for more bags.
This all being said, each bag will work for the trick. Just be aware that with the white bag, the stirring stick is a bit more visible through the paper. Handle with a little more care...
Happy holidays all.
Enjoy your free download...it's a fun trick!
