When I started making minis, I mindlessly thought that 'pins were quite fine' - wrong!
(The same applies to sewing threads . . . )
The thickness of an ordinary sewing pin is usually about 0.55mm (or 0,55mm as it is written in Europe). This is not at all fine when you are talking about minis, as I soon found.
So the hunt began, and here are the results. In the photo above, from left to right:
1. Sequin pins. These are not particularly fine (they're about the same as sewing pins), but they are short and make excellent 'nails'.
2. Fine lace making pins - 0.45mm. These ones are short (17mm long) with flat heads. I bought these from Martin Burkhard in Switzerland - http://www.ateliermb.ch/
3. Patchwork pins 0.45mm. Clover brand, art #2507. These have glass heads so they won't melt if the iron touches them. Available from patchwork suppliers.
4. Insect pins size #000, approximately 0.275mm. These come in steel, or black enamel. I love these!! They are strong and flexible, and hold well in a bent position. Perfect for adding to fantasy orreries. I found mine on eBay.
5. Beading needles size #16 - approximately 0.25mm. These are very flexible, and almost impossible to thread without a magnifying glass! Would be good to cut short to resemble pins or needles in a mini sewing box. Available from some online beading suppliers.
