How to butterfly coil (aka lap coil) a slackline

So, you've just finished having fun on your new slackline. It's looks like it is ready to start to raining so it's best to take everything in as fast as possible yet not have a massive knot of webbing for the next day's play. What to do? Butterfly coil it! The butterfly coil is both fast, practical and can significantly reduce snags, kinks and knots in your webbing. If done right you can actually uncoil just the stopping knot and throw the main line towards your anchors and watch it uncoil nicely in mid-air.

While there are various rope / webbing management techniques out there, the single strand butterfly coil has proven the most effective for our use on any piece of long webbing. The double strand can be faster to coil but usually takes longer to deploy. The daisy chain while looking cool is slow and will still yields too long of a piece of webbing to manage. The mountaineering coil looks fashionable for TV shows but it twists the the webbing unmercifully, takes a long time and can cause cumbersome deployment. For short pieces of webbing the daisy chain or butterfly coil work fine. 

	To begin coiling your slackline take one end in your hand as shown. If you are coiling one of our kits that have permanently attached slings, begin with the sling side first and treat it as one long single piece.
	Begin making loops in your hand alternating sides. Ideally these loops will hang around two feet below your hand. Smaller loops will mean more coils but will be more compact when finished and the opposite for long loops.
	Continue making loops until you reach last four feet of the length of webbing or so.
	Holding your hand tightly in the middle, wrap the extra tail around the outside of the loops several times.
	Make sure your wraps are nice and tight against the webbing and are near the base of your hand.
	With the remaining tail, insert a bight (bend or loop) of webbing through the hole where your hand was holding the loops. This works easiest to place the bight in the hand holding the webbing and pull it through to avoid any webbing slipping.
	Now place the remaining tail through the loop that you placed through where your hand was.
	Pull it nice and tight and you've now butterfly coiled your webbing. To deploy for next use, simply unthread the tail, undo the few loops around the outside and you should be able to throw the webbing and watch it uncoil nicely in mid-air.
