This is a strong material, and support a lot of weight!
Step 1: The Pipe
Step 2: Cut the Pipes
In my case, I had a pipe with 130 cm (pipe 1) and another with 140 cm (pipe 2).
Then, I cut the pipe 1 in 4 pieces with 30 cm each (for the base -legs).
The pipe 2 was cut in 2 pieces of 70 cm (for the seat).
The ideal would be more 2 pieces to the base and more 1 piece to make the seat, but unfortunately I didn't have another pipe in my hands.
Step 3: Ajust the Pipes
Step 4: Fix the Pipes
I used hot glue, but you can use any glue that work with paper.
Be careful with the measures. Let a border about 5 cm before the base. If the semicircle don't fit exactly with the seat pipe, you can fill the empty space by using hot glue or even little balls of 'knead' paper.
Step 5: Multi-Utility
I don't make any ending. You can paint or paste rope to finish the piece.
You can make a sort of things. It's only a suggestion.
You can use like a bench, a table, a DVD support (increase the measure of 2 base pipes).
For example, large pipes can be used to make a bed.
Or playground toys or anything.
I have 2 large pipes that I use like columns and we to adorn in December.....
Use your imagination and good work!
