The pieces of electrical tape mentioned below should all be roughly four times longer than they are wide. You can't see the full length in the photos, since they are folded under.
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.
As mentioned earlier, there's more kite making on this site than you can poke a stick at. :-)

The Big MBK E-book Bundle is a collection of downloads—printable PDF files which provide step-by-step instructions for many kites large and small.
That's every kite in every MBK series.
