The Lemon Ice foam (2mm thick) is closer in color to Eastern Green Drakes I?ve seen than any olive, so I sliced off some 1mm strips; that never creates uniform thickness for me but it works well enough.

hook - WFC Model 28 #10
thread - Danville 6/0 light olive
core - 15 lb mono
tail - moose body
body - 1mm foam lemon ice
wing/thorax - deer hair dyed olive
shoulder - pheasant rump dyed chartreuse (1 Tbs Rit Neon Yellow/1 cup water)

Regards,
Scott
