Whip #65
Had a whole day to work on this. Quite a rare event! 
Whip #65, 6' bullwhip, 10"x 1/8" fiberglass handle, BB and ball chain core, 8 plait belly with 14 plait overlay in a dark blue with a lighter blue accent stripe and white interweaving for the knots. The core was made at the same time as whip #64 but this one uses less lead tape and has more build up on the handle to make it thicker. Also used the loop ended fall with the overhand knot fastening at the point here. It seems to work well enough despite the added bulk to the point.
The colours were requested to match the Toronto Argonaut colour scheme.
I like doing interweaves on my knots now. I can make the knot foundations a little bigger and any gaps are corrected by the interweave itself and having the extra material causes the main knot to tighten up. I got to play around with using string and glue for the knot foundations as per Rhett Kelly's instructions. Seems to work pretty well and it's no slower than my original method.
