Welding plastic bags

Step 2 Stack materials

Place the first piece of plastic on some oven paper and mark the place where you want to make the seam. Then place the other piece over the first one aligning it with the mark.
The plastic sheets are slippery and they like to escape. You can make them stick in place by wetting them just a bit.
Now place another piece of oven paper on top of the plastic. You should be able to see the markings through the paper. This is why it is a good idea to use light colors and avoid black plastic.

is "oven" paper the same thing as wax paper?

In this context, I would think that "oven paper" would be the same as parchment paper. The difference is that parchment paper is coated with a thin layer of silicon and can withstand the heat of the oven.  Waxed paper would melt.
