For this Delta, you need eight 30cm (12") bamboo BBQ skewers.
Also, you need to cut off four short 0.15SL (4.4cm, 1 3/4") lengths of skewer. Plus a 0.30SL (8.7cm, 3 1/2") length, which joins the spreader in the middle.
The next photo shows how these are all glued together. Note how the spreader has a pen supporting the middle while the skewer tips remain touching the floor.
The other pairs of skewers are just lined up straight, flat against the table top, with a point at each end. Check each one...
To make sure there is no kink at the join, get your head down low and look along the skewers. Shift one a little, if necessary, before the glue dries!
The pieces of electrical tape mentioned below should all be roughly 4 times longer than they are wide. You can't see the full length in the photos since they are folded under.
Take one of the straight pairs of skewers that remain, and line up one end up with the short upper edge of the upper tab, as in the photo below...
If necessary, snip the skewer to length at the lower edge of the lower tab. These skewers are a leading edge spar.
Attach the bamboo to the sail plastic with a length of insulation tape, just like the bottom end of the vertical spar. See the photo over there.
With clear sticking tape, tape down both the tabs.
Now do the other side exactly the same. The photo below shows the two leading edge spars and the vertical spar in place, with all the tabs folded over and taped down...
The remaining pair of skewers will form the spreader, which keeps the leading edges apart in flight. To keep the tips off the table or floor, you will need to place the kite on an object such as a book...
