Propagate these easily by putting them in a cup of water. When they grow roots pot them up in cactus soil mixed with perlite for drainage in a plant pot with drainage hole. This is a high light plant so put it on a windowsill in front of a south/west/east facing window. Water when the soil is completely dry. Pruning causes it to branch out.
I'm just gonna give all the cuttings to one person who can share them out as they please.
