Vertical Corduroy Stitch produces a striped effect in the canvas. 

It is made up of alternating vertical rows of Tent Stitch and Satin Stitch slanting over two canvas threads. 

This stitch can also be worked horizontal. The diagram for that can be found here. 
 


The above example was stitched in Pepper Pot Silk.
