Hi kendyann! I keep mine covered between two layers of wet paper towels. You can put some tape along three edges to make a pocket. Don't expose the cuttings to direct sunlight if you can help it. Woodier cuttings tend to last longer wrapped in paper towels than succulents, like Christmas cactus or aloe.
Lay out the pocketsin a warm but well-shaded place. We have a potting table in the garden shed. If just outside in your yard under a tree, weight the corners down with small pebbles to keep a strong breeze from blowing them away. Spritz the top of the pocket well to keep them nice and moist then every time you water plants.
Depending on what it is, the ends can deteriorate fairly quickly sometimes. When you are ready to plant, trim the ends to expose healthy stems to the rooting hormone or soil. Plant them in half soilless/half perlite as soon as possible. Hope your cutting do well!
