While grafting/budding is the industry standard, I suppose, you can, and I 
have, rooted mulberries from cuttings.  As they are a member of the 
Moraceae, dormant-collected cuttings should root quite easily, similar to 
the way figs are propagated, though I've had best success rooting 
semi-hardwood cuttings, taken in late July-August, dipped in talc-based 
rooting hormone, stuck in a 50/50 mix of sand and peat, and placed in a 
shady spot, watered daily, with willow water.  I usually cut them back to 2 
or 3 leaves, and cut off about half of each leaf.
Success rates have been reasonable, considering the low level of care mine 
usually receive.
