Seat the spars fully in their fittings. Take care not to slip and poke a hole in your kite with a spar. If your kite has standoffs, you may need to line the fittings up along the spreader spars.

A slippery fiber, Spectra feels smoother than Dacron when lines are wrapped around each other. Spectra has a low melting point, causing it to break if it crosses another type of line, even cheap cotton line. Blended Spectra lines are braided of Spectra and Dacron fibers. Sleeving is a length of hollow braided Dacron put on the ends of line before it's tied. You can get line pre-sleeved or get a sleeving needle and do it yourself.
