I don't want to disappoint but the detached body daddies don't use raffia. When wet it goes too soft to be a body.
Raffia is used on traditional wet daddy patterns tied on long shank hooks.
Daddy "Long Legs" (wet dressing) (By Highlander)
hook:10-12 L/S
thread:brown 6/0 waxed
rib:fine gold wire
body:brown raffia (wet with saliva before winding as it makes it easier to work with & create a nice ribbed effect)
hackle:brown Partridge
front hackle:Gold Pheasant tippets,wound on "full"
It also makes great bodies for wet mayfly patterns.
For a detached body you ideally need something that floats. Foam cylinders are best, Deer hair is excellent or you can use or make your own pre formed tails and tie them in. Here are a couple of examples
