7-club three-count (966). A good pattern to practice doubles. Provide feedback about incoming doubles (e.g., over/under-spun, short/long, high/low, wide/narrow). As the pattern gets more stable, try to look down to see your passes land.
7-club Jim's two-count (9964966).
972. A great pattern to combine singles and doubles, one of them crossing, so both thrown to the same hand ("stacks"). Note: Juggler A starts with one club in the right hand and two in the left.
Not likely (96672). Doubles in period-5 patterns can be tricky, make sure they are lofty and use the self-zip-self to stabilize.
Funky bookends friend (96677). Harder version of not likely, keep the double high.
8-club pass-pass-self (996). A great introduction to ambidexterious 8 clubs.
