You're doing it right.  The instructions call for wire lengths that leave 
fairly long tails, like 3", which come in handy for suspending the coil in 
a pot to boil it for a while.  Reasonably tight without getting too 
aggressive with pulling the wire is the idea.

Wind the toroids snuggly.  When you are done they should look like the
ones in all the photos on the web site.  1.5 to three inches left over
is about right.  They purposely specify wire lengths a little long to
make it easier to wind the last few turns.  Leave the leads at least a
1/2" long when you strip them so that it's easy to thread the ends into
the board and snug down the toroids by gently pulling on the lead on the
far side of the board.
