What you need
Two long sturdy bamboo poles. Mine were approx 38mm wide by 180cm tall.
6 smaller bamboo sticks. I used 3 long stakes approx 90cm long by 20mm wide. I cut them in half.
Natural looking twine.
A pair of scissors
A small saw
Step 1: Step 1
If you are cutting bamboo sticks in half, measure before you do so. It doesn't need to be perfectly accurate, but all rods need to be approximately the same size.
Use sandpaper to saw off any rough edges.
Then measure out your poles so your cross poles are spaced evenly over your tall poles. I made mine approximately 30cm apart Try to be as accurate as possible.
Step 2: Step 2
I found this excellent page on how to tie the not.
As you can see from the photo, I added a cross in the middle.
This cross is not necessary for the ladder to be solid. I did if for decorative purposes only.
If you are following the page on how to tie a square lashing, between step 12 and 13, I wound my twine diagonally across the top of the small pole, then straight under the upright a couple of times to get the effect.
Lash each cross pole onto the uprights, the same distance apart. Make sure your uprights are parallel.
Once you have finished your knot, trip the loose ends to make it neat.
Step 3: Finishing Off
Simply hold the upright tight, and maneuver the cross pole to where you want it. You may have to wiggle it a little. Once you're done, you can lean it against a wall and hang things on it.
Unless you use extremely strong materials and your lashings are fantastic, please don't attempt to actually use it as a ladder.
