Need thread about 0.1mm in diameter

[Doug McKenzie]

I have only been able to find thread down to 0.3mm and I'm working on a Leon-in-a-bottle model at 1:300 which requires some 0.1mm tan thread for running rigging.  Does anyone know of a source for thread this fine?  I've attached a picture that shows the peak halyards as 0.3mm black and you can see that it is way to heavy.  The hull is about 4" long.

 

Thanks in advance.

You could try fly tying thread. It comes in many colors and thicknesses.

I have used 0.1 mm line from Amati.

Fly-tying line should cover what you require. I have been using it with diameters down to 0.05mm. I am in the UK so my sources are not relevant, but you will find plenty of US suppliers.

Thanks all!  I found some on Amazon - I don't know why I couldn't find this the first time I was looking.
