Everything about 150/12
Open the question you have. Full guides on texsolv.se.
What do the numbers 150/12 mean, and how do I measure?
The first number is the length, 150 mm (5.9"), the second the eye, 12 mm (½"). To check an old heddle, stretch it gently between two sticks against a tape measure and read the full length. Don't measure a cut piece.
Which colours, and what are they for?

One colour per shaft makes the threading readable from across the room and shows at once where a heddle belongs when you add or move one. A colour can also mark a border or a stripe in the warp.
150/12 comes in all seven colours. Colours are made for 150/12, 160/12, 205/12, 220/12, 237/12, 268/12, 280/12, 318/12, 330/12, 392/12 and Mirrix. Other sizes are white only.
Colours on texsolv.seHow do I mount and thread them?

Slip the tied bundle of 100 onto the heddle bars, untie and distribute. Cut ends never need fusing. To thread: fold the warp end, push it through the rectangular eye with a finger and pull through. Easy right- or left-handed.
Made a mistake in the sequence? A new heddle can be inserted at the correction point without re-threading the shaft.
Which looms use 150/12?
Not sure? Measure an existing heddle, or look up your loom in the guide.
Can I wash them?
Yes, in lukewarm water with a mild detergent, preferably tied together in a laundry bag so they do not tangle. Let them dry at room temperature; do not iron or tumble-dry.
