Referred to as "Scud Back". Cascade's translucent "Body Stretch" is a full 1/4" wide in its relaxed form. It will stretch down to a 1/16’ and is tuff as nails. Scuds, nymphs or as a "wiggle tail" this is the material. For a simple set of frog legs with a lot of movement, simply tie a overhand knot and serrate the end "presto". 2 1/2 Yards
