Learn how to build a Diamond kite by making and flying the MBK Simple Diamond.Simple Diamond in flight

Don't worry about how long this page looks....

The steps are easy, hence this simple Diamond kite comes together very quickly!

Sometimes I go out with my young son to fly this kite. A classic picture of father and son, out flying a kite!

Like nearly every Diamond, it's very reliable and easy to handle in flight. Watch it wing-waggle and swoop occasionally, staying up as long as the wind blows.

The tail is simplicity itself - just a long slim rectangle of the same plastic you use for the sail.

NOTE: Video views from this website don't appear to be counted.

This simple home-made design excels in Light to Gentle breezes.

1. How To Build A Diamond Kite -
Measuring The Sail

You might want to take a quick look at the materials and tools for making this kite, first. Then just click the Back button on your browser to get back here.

The Simple Diamond - measuring up the sail.
  • Place your plastic bag flat on the floor, with the closed end at the top.
  • Starting from just below the top-left corner of the bag, measure and mark 3 dots on the plastic. I've high-lighted the dots in yellow, in the photo. Judge the horizontal and vertical directions by eye. If you're careful, there's no need for a T-square.

2. How To Build A Diamond Kite -
Cutting The Sail

The Simple Diamond - marking the template shape.
  • Take your ruler and connect the dots with the black marker pen, as shown in the photo. (OK, the lines appear a bit faint in the photo!)
  • Flip the plastic over and trace over all the black lines.

The Simple Diamond - complete outline.
The Simple Diamond - the sail cut out and edged with tape.
  • Cut along the top and right side of the bag, and open it out to show the complete sail outline, as in the left photo above.
  • Take your scissors and cut along all the black lines. As in the right photo above, your Diamond kite sail is nearly complete!

3. How To Build A Diamond Kite -
Adding The Spars

The Simple Diamond - cutting the dowels to length.
The Simple Diamond -  close-up of a spar tip .
The Simple Diamond - both dowels taped in place.
  • Lay a length of your 5mm (3/16") dowel down the center-line of the sail, line it up with the top sail corner and saw it off at the bottom corner. See the left photo, above, where the dowel has not yet been cut.
  • Cut off a 5 cm (2 inch) length of insulation tape, and stick down the dowel to the plastic. See the right photo, above.
  • Do the bottom end of the dowel the same way.
  • Do the other dowel similarly, so the kite looks like the photo on the right.

Note: After flying this kite for several months, I now recommend you add another piece of tape to the top corner of the sail, at right-angles to the first tape. For added strength!

4. How To Build A Diamond Kite -
Attach The Flying Line

Try this Stake Line Winder from Amazon, if you are not sure where to get suitable flying line. The 30 pound strength is ideal for the Simple Series or Soft Series kites.

The Simple Diamond - flying line attached to dowels.
  • Poke a hole in the plastic sail, right over where the dowels cross each other.
  • Thread the free end of your flying line through the hole, and tie it firmly around the crossing-point, as in the photo. Ignore the loop in the photo, unless you want to make a simple bridle like I did...

5. Rather Important!
Attach The Tail

The Simple Diamond - close-up of tail attachment
  • From spare scraps of sail plastic, make up a long narrow strip no shorter than 5 times the length of the kite itself. The strip should be about 5 cm (2 inches) wide.
  • Thread one end of the tail around the bottom of the vertical spar, as you can see in the photo. Tie the tail to the dowel with a simple knot.

And Now - FLYING!

The Simple Diamond kite cavorts with the clouds...A perfect day for it

I hope you enjoyed learning how to build a Diamond kite. There's ours in the photo above, flying around on a perfect day for it.

Out In The Field

Diamond kite stories of my real-life flying experiences are worth checking out!

Illustrated with photos and videos, of course.

That's it, you're ready to fly. Take the kite out whenever you can see leaves moving in the trees or bushes. If it won't stay up, try letting out plenty of line and then towing it up at jogging pace. It might find enough wind higher up.

With plenty of wind, this kite will waggle from side to side, so make sure all the tip-tapes are pressed down firmly and secure. I had one let go once, which brought the kite down suddenly. With some spare tape I had handy, the sail tip was soon fixed and the Diamond waggled straight back up to full flying height.

Ever Made This Kite?

You've probably read a kite-flying story or 2 of mine, after they appear under the "what's new?" link on this site. I sometimes wonder if anyone else has made and flown this particular design...

If you feel your efforts really paid off when the the kite finally got airborne - please type a few paragraphs in here telling us all about it!

P.S. I can only accept stories of at least 300 words. Just mention a few details like the weather, onlookers, the kite's behavior and so on - 300 words is easy!

E-book special of the month (25% off)...

This printable e-book takes you step-by-step through making a 120cm (4 ft) diameter Parasail kite. This kite performs well in gentle to moderate wind speeds. That's from 12 to 28 kph or from 8 to 18 mph. It pulls hard for it's size, so should not be flown by very small kids!

Every kite design in the MBK Soft Series satisfies the following points...

  • Materials are plastic sheet, tape and line – and nothing more!
  • Tools are a ruler, scissors and a marker pen - and nothing more!
  • All cuts are along straight lines.

For the greatest chance of success, I make recommendations regarding the materials. For example, the type/weight of plastic, type/width of tape and line type/strength. Close enough should nearly always be good enough, since the design is well-tested and should be tolerant of small differences from my original.

Get the e-book for making the MBK Parasail kite. After making your first one in plastic and seeing how it performs, you can try soft Tyvek or rip-stop nylon for your next build.

The e-book is a PDF file - which means printable instructions to refer to while you make the kite. It also means convenient off-line access if that suits you better.

"Love the easy to understand step by step instructions, made from next to nothing materials and above all so much fun to fly... cheers Tim for sharing your well thought out pdf kite designs with the whole world.

Very satisfying making your own and watching them get air-born for the first time."


"I've just bought your super e-book and spent most of last night pouring through all the great stuff in it!

Very detailed and USEFUL information - thanks for such a great book."


"30+ years ago, I tried making a kite using the 'instructions' in a free kite-safety booklet. What a disappointment for a young boy.

 Your instructions and methods are wonderful. You help the builder to focus on accuracy, without making it hard. Also, you use materials that are durable, yet cheap!"
