Heffs
From jugglingpatterns
Heffs are a throw to the same hand that threw the object, as a one-person (2-hand) siteswap usually represented as a "4", i.e. there is one throw from that same hand (and two throws from the other hand) before the object ist thrown again.
"Beginning Heffs" first tells you some patterns to start practicing heffs in your solo juggling, then how to incorporate sequences with heffs as tricks into common passing patterns. The next steps are probably the 5 club and 6 club why-not patterns from the why-not family (with passes, not with zaps) and finally the popcorns with "heff,heff" - which can also thrown with triple-self,single-self instead of the heffs, giving a nice pathway to triple selfs.
