I can remember Wally Boyce - who specialised in knitted rope tricks - performing an outstanding routine, very similar to this quite some years back.
The good news is that to perform a really visual and fun routine, all you need is a One Handed Change Bag, which we can easily supply if you don't already own one.
As for a routine, may we suggest that you take a look at the video as it will give you lots of ideas for bits of business, and, with a routine like this, the bits of business are priceless. Remember: there's a huge difference between time-wasting and time-filling. Time-wasting is exactly what it sounds: a waste of everyone's time, whereas time-filling is being entertaining and adding fun bits along the way. The journey is every bit as important as the destination, so make the process of the ropes changing as much fun as possible!
