The Origami Forum

Hi. I have just checked out the roll of foil paper (silver) i got from origami shop in order to compare it to my own kitchen aluminium foil paper and surprisingly enough they are different. The one i got from origami shop felt like it has a paper on one side and the colors of each side is different. One is silver and the other kind is kinda brighter and the one i have at the kitchen felt like pure aluminium on both sides and the folding on them feels different as well (and by the way the silver cutted foil paper i got fryesthe shop felt the same). Am i right in my assumptions? And if yes. What is better to suit pasting tissue paper on one side for complex models (making tissue foil paper) or maybe both do. How in generally is the use of each one of those different please elaborate. Thanks a lot.
