This is surprisingly hard, but there is a useful trick. Just as Zig Zag
is often described as "throw your right hand in" (that is, turn 1/4 so that
your right hand is toward your "tandem partner"), Trixie can be described as
"throw your inside hand in". Whichever hand you have joined with your
lateral partner, turn 1/4 to join that hand with your original tandem
partner, who becomes your new lateral partner.
Trixie Spin has 3 parts: Trixie, Cast Off 3/4, and Centers Cross Run.
