Here are wrappers, I made up, they fits around a 1.55, 4.25 and 6.8 oz bars, then I crimp the edges.
This prints on a 8 x 11 piece of paper, use what ever color you want. I just trimmed off the extra paper, and used double sided tape. And crimp the edges to make them look more packed. This is what the wrapper would look like when it is fitted around the bar and crimped.
