Travel sewing kit (with needle holder)

thingiverse

Holds two pre-threaded needles. Perfect for travel. If your needles are longer than ~35mm then stretch the axis I tie a knot in the end, place the needle in the tray and then wrap around. This holds the needle in place. It doesn't unravel easily, however I just pop it in a little zip lock bag, or you could use masking tape or glad wrap. I use one darker colour and one lighter colour thread. When I've finished sewing the button I just cut it with anything mildly sharp, at worst you could run it against something slightly abrassive, like a brick edge.
