The only materials required for this design are

  • 1 sheet of plain copier paper. A4 or Letter size. Use colored paper if you want to!
  • 18mm (3/4") clear sticky tape. In a dispenser preferably. Narrower tape would be even better, if you have it.
  • A light plastic bag, at least 45cm x 30cm (18" x 12") before being cut open. I used large-size freezer bags. 
  • Any polyester sewing thread, preferably the lightest available.

The tools required, if you can call them that, are

  • a pair of scissors
  • a ruler
  • a straight edge longer than 45cm (18")
  • a ball-point pen
  • colored permanent markers

Note: In the photos below, yellow lines have been added to make clear where the edges of sticky tape are.  

 


Step 1 - Make Sail

Making the Indoor Sled kite - Step 1aMeasured and dots marked

  • Lay down a plastic bag, and smooth it out to remove the most obvious folds and creases.
  • Measure and mark dots as indicated in the photo.

Making the Indoor Sled kite - Step 1bBag flipped and dots traced
  • Flip the bag over.
  • Mark dots over the ones showing through the plastic. To the left in the photo above.


Making the Indoor Sled kite - Step 1cBag cut and opened out
  • Cut the bag along the sealed edge, to open it.
  • Cut the bag along the opposite side to the side with 4 dots.
  • Open the bag out into a single flat sheet, with the dots on top. In the photo you can see all 10 dots. 

Making the Indoor Sled kite - Step 1dAll lines drawn
  • Rule lines between the dots as shown, to complete the sled shape. Be careful to go through the correct dot at top center!



Step 2 - Decorate Sail

Do you have permanent colored markers? Time to take them out...

Making the Indoor Sled kite - Step 2aDecorated with permanent markers
  • My approach was to put 1 cm (3/8") wide colored stripes down each side of the center-line, 0.6cm (1/4") apart. Followed by a 0.6 cm (1/4") wide border of black all around on the inside of the sled outline. See the photo.
  • You do whatever you like! Just try not to add too much weight though. Doing 'sparing line art' is how to make an indoor sled kite look good and minimize weight.

Making the Indoor Diamond kite - Step 2bSled shape cut out
  • Cut all around the sled shape with scissors. Cutting thin plastic can be tricky so take your time. Sharp scissors help!
  • From here on, we will refer to the plastic piece as the sail.


Step 3 - Make Spars

Measure And Draw

Making the Indoor Sled kite - Step 3aDots measured and marked
  • Take your sheet of paper and mark dots as shown.

Making the Indoor Sled kite - Step 3bLines drawn
  • With ruler and pen, connect the dots as shown.

Laminate And Cut Out 

Making the Indoor Sled kite - Step 3cTape laid down over shapes
  • Lay down sticky tape to fully cover the shapes. A small amount of overlap is OK, if your tape is narrower than shown above.

Making the Indoor Sled kite - Step 3dTape laid down over shapes, reverse side
  • Flip the paper over so you can add tape to the reverse side of all the shapes. It might help to place the paper up against a well-lit window, to trace the corners. Another way is to poke holes through the paper with a pin, at all the corners. Then you can see where all the shapes are.


Making the Indoor Sled kite - Step 3eSpar pieces cut out
  • Cut out all the shapes, as shown.

Join Rectangles

Making the Indoor Sled kite - Step 3fRectangles joined, long to short
  • Lay down the rectangles end-to-end, in long / short pairs as shown.
  • Check the alignment with a straight edge such as a ruler.
  • Tape the pieces together at the join. Use just enough tape to go once around the entire join.

Fold Lengthwise

Making the Indoor Sled kite - Step 3gSpars folded
  • Fold the 2 rectangles in half down their lengths as shown.
  • Crease the folds sharply. Pinching between thumb and fore-finger gets the fold started. Then you can sharpen the fold by using your thumb-nail as well.
  • What you have now is a pair of main spars.

At this point, you're about half-way through learning how to make an indoor sled kite!



Step 4 - Attach Spars

Tape A Main Spar

Making the Indoor Sled kite - Step 4a1 main spar in position
  • Flip the sail so the art work is against the table.
  • Take 1 main spar and align one end to the top corner of the sail. Make sure the join in the spar is closest to the bottom end of the sail. Also ensure the fold angle is 90 degrees or a little less.

Making the Indoor Sled kite - Step 4bSpar taped on, at nose end
  • At the top corner of the sail, place a short strip of sticky tape across the fold line of the spar.
  • Gently press down on both sides so the tape goes down then across to the left and right.
  • With scissors, trim the overhanging tape flush with the sail edges. See the photo.


Making the Indoor Sled kite - Step 4cSpar taped on, at middle and tail end
  • At the bottom corner of the sail, lay down and trim a strip of tape in the same way as before.
  • Also place a 2cm (3/4") strip of tape over the spar at the mid-point. See the photo.

Making the Indoor Sled kite - Step 4dBoth main spars taped on
  • In a similar way, lay down the other main spar, ensuring the fold angles are 90 degrees or a little less.
  • Apply sticky tape at the top, middle and bottom, just like you did for the first main spar. See the photo.


Step 5 - Attach Flying Line

You have pretty much finished learning how to make an indoor sled kite at this point!

Making the Indoor Sled kite - Step 5aThread laid down and taped at 1 corner
  • Cut off about 120 cm (47") of polyester sewing thread and lay at least 5cm (2") over a side corner of the sail.
  • Stick down a 5cm (2") length of sticky tape over the thread, as shown in the photo. Fold the overhanging corners of the tape around the sail edges.

Making the Indoor Sled kite - Step 5bThread attached at both corners
  • Do the same at the other side corner, with the free end of the thread.

  • Tie a Loop knot into the center of the bridle line. By aligning the side corners of the sail together, you can be sure of finding the middle of the thread. See the photo, where the Loop knot is to the right.


Step 6 - Flying!

Making the Indoor Sled kite - Step 6Indoor Sled floats up

This is a very low-speed kite and it will effortlessly float up at walking pace. Be careful not to jerk the thread or pull too quickly, since this will promptly fold up at least one of the spars!

If a spar does fold up, don't despair. Just carefully pinch the paper where it failed, to get it back into that V-shape section once again. Then try again, going a little slower or smoother this time.

The Launch Technique

This is how I like to launch, on a length of thread equal to your shoulder height...

  • Lay the kite flat on the floor, with the thread on top of course and the tail end pointing at your feet.
  • Lift gently straight up, while taking a couple of quick steps backwards.
  • If the kite appears to be rising, turn around and walk forwards while looking back over your shoulder.
  • Within seconds, you should see the kite floating behind. Walk a little faster to climb the kite, slow down to descend. It's a fine balance!

If you have the space, try letting out more thread and adjusting your speed until the kite cruises along just short of the ceiling. Look out for light fittings and so on. Look where you're going too, from time to time ;-)

If you need even more line length, just tie on more thread and wind it onto a small square of cardboard.

I hope you have enjoyed learning how to make an indoor sled kite this way.



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!
