G770 interlining is woven medium weight made from synthetic fibres.
The bulky yarn gives this interlining a really soft surface to be used on front parts of jackets, waistbands on skirts and trousers, perfect on medium to heavy weight fabrics. If making a linen jacket I would personally interline the whole garment with this product.
Apply to fabric by pressing the iron on step by step for 8 seconds, do not push the iron. Allow the item to cool down then lift to your ear and gently pull at the fabric if you hear a cracking noise then interfacing needs more heat to adhere to the fabric.
