I know this is an old thread but and don't know if you have found a source for paper but if you have not it is fairly easy to make. To make slow match with paper you immerse paper in a warm solution of kno3(Potassium nitrate) and water. Use a solution of 1 pound of kno3 to 2 gallons of water(you can use less if you don't need so much just keep the same ratio of kno3 to water) Once the paper has soaked in the water for a little bit just pull it out and let it dry. An easy source of kno3 in the US is stump remover, it can also be found as a food additive it is used in preserving meat(jerky).
