Thanks for information. I just bought some to try out. However, you said upthread that brown stuff is more expensive and I found that at least from the source I used it was cheaper than the green stuff. Not sure if the packaged quantities are the same but in anycase the price of either won't break the bank,

Hi,

the quantities are different. Browns stuff is sold in a 4" strip while the green stuff is sold as 2 50gr rolls which in it's old form was a 36" strip. So Brown stuff is about four times as expensive.

Have fun experimenting and feel free to ask questions if needed.
