T- Stitch is a great background stitch to keep in your pocket. 

It is a light coverage stitch which means you will see some canvas through the stitches. This is intentional. 
T-Stitch is best worked in a fine thread like Petite Silk Lamé Braid. 



The example above is done in Threadworx Overdyed Metallics.
