Oh yeah - paper thickness - available in many thicknesses - down to about .009"- onion skin (4 layers). Some guys, looking for really thin patches, use Simplicity patterns (clothes making).Some outfits like Buffalo Arms in the States sells patches or patch material. buffaloarms.com, I think. They will also mail Kroil Oil for those who can't get it locally. My 'late' buddy Brad ordered some with some other stuff and Customs let it through into Canada.
