#20 scud hook makes an approx size 14/16 fly. A longer, wider-gape, standard-length hook represents nearly twice the metal weight for the same size fly.

Aleene's Flexible Stretchable (that's a brand name) fabric cement keeps it from unraveling, yet still soft flexible and bendable.

Floats like a mayfly. Stings like a hook.
