¾ and full-canvas interlinings are stitched to the seams of ¾ of the jacket or the entire front of the jacket from the shoulders to the bottom hem. ¾ and full-canvas interlinings are preferred over ½ canvas interlinings because they add body and drape to more of the suit or sport coat. Canvas interlinings can be fused or hand-stitched. Fused interlinings create a more rigid appearance, while a hand-stitched full canvas promotes more natural movement. Hand-stitched interlinings are the most expensive and difficult to construct.
