The Blob is a fritz mini-lure and works superbly when fished very fast but can also be used on different methods of retrieve. The pattern can be tied in a mass of colours from dark to very bright on the colour spectrum. The darker coloured fritz's are usually fished more slowly than the lighter coloured ones.
This blob is designed around a traffic light (Red, Amber and Green) and is very effective.
A new method for reservoirs and stillwaters is to fish the blob under a bung or large dry fly static and wait for a take.
