I have had good success in growing many things from cuttings, like hibiscus and frangipani (plumeria), by dipping the stem in honey and putting the cutting into sandy potting mix mixed 50/50. If the weather is cold to cool, a plastic bag over the pot gives a hothouse style of growing.
Hydrangeas grow easily from cuttings too. Make sure there is a least 3 eyes (leaf nodes). The bottom one should be placed in the soil (I use potting mix) and this is where the roots will grow from, Also cutting off any large leaves is important so all of the plants energy can go to making roots.

The kids old sandbox makes a great place to grow cuttings for starting new plants! Be sure to shade the new cuttings from the sun and water frequently until you see new growth. These little plants you are growing will sell for $5.00 each at your next garage sale!
I save all sorts of small glass, and plastic, bottles, fill them with water and use them for rooting cuttings. It is a very productive and interesting pastime, looking to see how the roots develop over time.
I have used several methods for starting plants for my own use. I once moved on to property that had no trees. Early the next spring, with the blessing of a neighbor, I clipped very thin branches that where long and straight and more then 3 ft long and had buds barely cracked.
Pull the branches down away from the bush so they will lay on the ground. Do not cut but scrape away the bark where it touches the ground.
