Using an electric dryer may be more convenient, but the electricity cost is high and the sun’s rays are free. Most people use bamboo poles to put out their clothes to dry in Singapore.
We also call these multi-coloured poles gala. There used to be a gala man who would come by in this truck and toot his horn. If you needed extra poles or new covers, you could then buy it from him. The plastic cover is made to tighten around the bamboo pole with the application of boiling water which makes it shrink. Anyway that’s what I recall seeing as a child.
They do seems a tad dangerous to me though, and you need to keep a secure grip on them. I’m sorry, but if it were up to me and cost was not a factor, I would chose a dryer. I used a dryer once in Australia and I found it just so convenient.
