If you don't want to use a plastic bag, an easier and more 'effective' method would be to use a pillow case. This will allow the scents to dispurse more rapidly, and evenly. Just remember to wash the pillow case in the same scent killing detergent you was your clothes in, such as baking soda. The pillow case filled with dirt, leaves, pinecones, etc. works great for scenting your clothes like the forest you hunt in.
