Kirk,
I start with using thick foam, say 5mm or 3/16th" on #14-16 1XL, say 6mm or 1/4" wide and 3mm or 1/8th" for #16 standard or #18 1XL, a little thinner. Tie in point of the foam is clipped to a point and tied in front of the abdomen, wrapping toward the eye so as to bulk the thorax a little with the tie in. The thread is then returned to the base of the foam "post" (at this stage the foam is sticking up from the hook shank in front of the abdomen like a parachute post), thorax is noodle dubbed on the thread, wrapped short but rather full with a fur containing good guard hairs that does not easily crush and retains a bulky- springy effect, ensuring to leave a good distance from the front of the thorax to the back of the hook eye- to tie off the foam and wrap the hackle.
Then bring the foam over the thorax, but DO NOT pull it tight, it must lay loose over the thorax- retaining all the original loft of the open cells of the foam. Sometimes, to get that really "full" effect, I will pinch the foam lightly between thumb and first finger of my left hand (off hand- right if you tie left handed

) and actually ease the foam back a little, then wrap in over the foam, in front of the hold point of thumb/finger to tie it in place. Throw 3-4 tight wraps over, trim excess foam, wrap some more to trap down the bulge where the foam has been cut and you should be ready to wrap the hackle as per normal.
Often when using foam in similar ways, there is a desire to pull the foam over the thorax toward/over the hook eye with the right hand and hold it in place under tension while we flick the bobbin holder over the hook shank a couple of times with our left hand to hold it there. This will flatten the thorax and compress the open cells of the foam, leading to a neater, flatter more regular looking wingcase- but less floatation or illusion of swelling wing buds about to break free.
Hope this helped? If not I may be able to cobble up a shot by shot photo series........ but I can possibly explain it better than my crappy photos could!
