Hi to all .....
Figured out a way to practice tying Half-Hitch, Whip Finish and other thingys without using a HOOK .
Photo will show how a PAPERCLIP cut into the shape of a hook will work just fine ... plus, when I'm done with that knot ... I can just slide it off with my fingers (no hook eye) and start over !
Also, with the type of vise I have and the added bobbin holder .. I have a place to hang that evil tool "Whip Finisher" close by till I need it.
Hope this 2 ¢ worth is of use to you.
