Video in the article is pretty straightforward. I have tried it myself with 0.35 mm fishing line, but I haven't got a heat gun, and that was a huge problem. I've tried to heat the coil with lighter, but it's really difficult to control the temperature. If it's too low, coil does not contract, if too high - melts immediately. But one of about ten attempts was successful, so it definitely could be done at home.

Do you have a hair dryer? If you can actually use a cheap heat gun, Harbor Freight Tools sells them really cheap in the US.

Yes, I do. It's not hot enough. Heat guns are also cheap here in Ukraine, may be I'll buy on occasion.
