The Tulip knitting gauge is ideal for measuring the correct knitting tension in knitting or crocheting work. It is a square ruler made of transparent plastic, so that all stitches are clearly visible, even if you place the ruler on your project. The knitting gauge measures 10 x 10cm and has a central section of 5 x 5 cm in the middle. The dimensions on the outer border are indicated per millimetres and on the inner section per half centimetre
