As I so often say, what is a "Bluegill Bug without some form of Rubber Leg or Silicon Leg, anyway?"
Using Rubber Legs or Silicon type legs are very, very common in tying Bluegill Bugs!
The Zuddy Mini-Leg Puller is just the tool you need to have available when you want to insert leg material through Foam or other material to anchor those legs in place. This very well built tool comes with a sharp point to insert through your foam etc,, insert a leg material and pull it back through.
Just like that! Permanent legs on your Bluegill Bug. I consider this an essential tool in my inventory of tying tools on my bench.
