This video shows a short variation of double hammock that can be done with one (or sometimes two) sizes shorter than your base size and ties at the shoulder. This is the version that starts centered on the wrap. The video includes 3 tips for getting a high second pass (jump rope trick, towel trick, and elbow trick) and also shows how to tighten the chest pass and a few options for tying off (candy cane chest belt, knotless).
