This is a carry I am learning along with you today! Searching YouTube, I have found a couple different variations, which I will share here.
The basis of the carry is the "wiggleproof" pass, which goes (contrary to reinforcement passes) UNDER the first leg and OVER the second leg, spreading the pass up and over baby's back.
Although this carry has similarities to the double hammock, unlike double hammock it starts with the middle marker at the center of baby's back.
The wiggleproof pass can be done first, as in this video: https://www.youtube.com/watch?v=Nj6TMjJuepg
Or second, as in this video: https://www.youtube.com/watch?v=Dxj7otVRcZs
If it's done second, the carry starts off identical to the double hammock.
