I prefer plain, white, new tissue paper.

that way, the item can be stored in it if needs be without worrying about any leaching over time. If it is to be popped on a shelf and put aside for a while, or just to keep things a bit separate.

glad wrapping first...hmmmmm...it's an idea but I will stick to plain white 🙂

I use glad wrap for other things 😉

As for including sweets, it is a "sweet" touch unless it is warm weather. There is a risk the little goodies melt onto the paid for item and the buyer gets unhappy. So maybe those, should go into a little ziplock.
