I agree with what WW said about taking a cutting from only one piece if you have two. Start by taking the top few inches off one of them. Lay that cutting sideways on the surface of some barely moist but not soggy wet sphagnum moss. Just nestle it in but don't bury the stem at all.
Put it inside something to keep the humidity up, like a large jar, or put a plastic bag over it. Don't let the leaves touch the sides of the jar or bag. If your home is humid you might not need this step, but not everybody has high humidity.
It should root and begin growing. The bottom part of the stem you cut should branch and you can do it again. Later when you have learned how to do it you can cut the bare stems into pieces with 2-3 leaf scars and do the same thing.
Like I said I would wait for warm weather.
Edit: Here is a photo of a jewel orchid I bought already rooted in sphagnum. There are water spots on the jar so my phone camera had trouble focusing. It's vertical in the pot because it already had roots. I have low humidity in my house so I put it into a large glass vase with plastic on top. There are clay balls in the bottom with some water to keep the humidity up in there. I put it on an inverted plastic food container to keep the pot out of the water so the sphagnum doesn't get too wet.
Next to it to the right is another jar terrarium for rooting an epiphytic cactus cutting.
