Step 1: Things you will need...
-A sheet of plastic that measures 33 1/2" by 24". I used a very large plastic bag but a sturdy black bin bag is about right too
-A smaller sheet of plastic measuring 19 1/2" by 26". This is about the size of a standard carrier bag, but again bin bags or any plastic sheeting is good.
-3 balsa wood dowels 24" long. I've used 6mm dowels, but larger ones will also work. Balsa dowels are available from craft shops and hardware shops, but if neither are available, garden canes are also a good alternative (the green sticks to keep plants on the straight an narrow)
-Sticky tape, double sided sticky tape and reinforced sticky tape. I used a heavy duty cloth gaffer tape, but gaffer tape or all weather tape of any sort will work well.
-Kite line and handle. Available from specialists and some toy shops and online. In the UK, Kite Shop has a massive range or stuff. A mid weight fishing line can also be used and is a bit cheaper and re-usable.
-Hole punch, scissors, marker pen and tape measure.
