Garden: Vine Support Structure using PVC pipes

Yesterday, I was thinking about ways to support the pumpkin vines.
I came up with a design today. I went to local Lowes store and bought

(1)3/4" X 5' PVC Pipe Plain X 6
(2)3/4" SCH40 Tee
(3)3/4" SCH40 Cross

I used my hacksaw and miter box to cut these pipes to 18" and 9" sections

I came across a good DIY on working with plastic piping

At the end of the evening, it was a satisfying experience.
This structure can be expanded in both horizontal and vertical directions.
