We don't wrap here anymore unless the rabbits are unruly or older than usual, my daughter just puts her hand over their eyes and holds their rump.
The way I wrap them is to first push their hindquarters well under them like an exaggerated show pose for compact breeds. Then pull the towel up over their rump and shoulders from behind, and flip the towel up from either side like you would swaddle an infant, except I cover their heads with the towel also, leaving only the ear exposed.
I am planning on attending a show this weekend so will probably be touching up tats on older rabbits. If so, I will take pics and post them for you.
