Many fly tiers avoid tying para on hooks smaller than size 18 because they have thick fingers or or find this to difficult.
bellow you can find an easy way to tie small CDC parachute:

Olive emerger

hook: Daiichi D1130 #20
thread: 17/0 UniThread
body: peacock olive quill
tail:cream fibers
hackle: olive CDC barbs

 

 

fix the cdc barbs with one turn of thread

fix the polypropylene fibers on the cdc barbs

fix the cdc barbs and polypropylene in X method

make 3 turns of thread on the base of the hackle to spread and fix finally the cdc barbs

 

 trim the polypropylene

trim the cdc barbs

and the small  cdc fly  is ready

 

 

Brown quill dun

hook: Daiichi D23 #20
thread: 17/0 UniThread
body: peacock brown
tail:coq de leon barbs
hackle: brown-dun CDC barbs
