This is a cheap and cheerful way of doing it, and could very well ruin your laundry iron (I used a cheap one I had lying around and it's steam nozzles were thoroughly blocked afterwards), but if you find yourself in the same position I did when I developed this technique, (college deadline looming, no wax paper ANYWHERE in shops, no time for internet delivery) you might just be willing to risk it.
You use wax crayons (I used white ones-I'm guessing coloured ones might cause colour transfer???) and any ordinary paper (I used tissue paper as I wanted it to remain flexible). Remove the crayon's wrapper, then carefully rub the crayon against the hot iron whilst holding the iron over the paper (you might want to protect whatever surface you work on) let the wax drip onto the paper, then press the iron onto the paper, rubbing the iron in circles on the paper. Repeat this process until the paper is covered with wax- it probably won't look pretty, but it will work. The basic principle is using heat to melt the wax into the paper. And no... Rubbing the crayon onto the paper and then ironing it doesn't work- I tried that ;).
Wet paper for 5 seconds and put it in front of a fan and it will feel like wax paper
Waxed paper is a type of paper which is made water-proof by the application of wax over the paper. Thus it is a type of moisture proof paper. It is said to have been invented by Thomas Alva Edison in 1872 but in actuality he just discovered a method of making such paper very cheaply but in a very efficient manner. The method of making such paper dates back to the medieval times.
Waxed paper is used for several purposes like cooking, craft making and art. Making waxed paper is a highly complicated and difficult procedure. It requires a great of expertise and practice. It is nowadays made in bulk quantities with the help of big and up-to-date machines which are made only for this purpose. I don't think that one can make waxed paper at home with the help of the rudimentary things available at our homes.
