These two rulers make it much simpler to prepare all types of seams, folds and pleats for sewing. The measuring, marking, folding and ironing to the wrong side can be done in quick stages with the aid of this practical helper. So that you can work easily with any size of fabric, Prym supplies the heat-resistant ironing rulers in two different sizes. Punched lines ensure exact transfer of the marking lines onto the fabric. On the front of both rulers there is a vertical metric scale, which is ideal for trouser and sleeve seams. On the back of the ruler there is a horizontal scale, which allows for perfect marking, folding and ironing of long, straight seams. The instructions printed and illustrated on the stencil are particularly helpful, when shortening trousers.
