Artic Rays can best be described as a wispy fringe. It has pieces of transparent fiber that give a glistening effect. Do not drag this yarn across the canvas. Use a larger than normal needle to prepare the canvas holes to accept the Arctic Rays without pulling it apart. The glistening effect of this yarn is more pronounced with long stitches, as less of the fringe is pulled into the canvas. Arctic Rays also makes wonderful French Knots.
Treasure Petite is a three ply braided metallic that is extremely versatile. It is very durable and should not present any problem when stitching. In fact, you might try using it where you would use two ply of blending filament. It would give the same look and you would not have the bother, or mess, of stitching with blending filament that you would need to ply up. It is great to use when you want to add a glimmer of metallic without overpowering the rest of your stitching.
Wisper is a very fine fuzzy single yarn. It is usually necessary to ply up to a thickness that will cover your canvas. It is OK to double this yarn over in your needle. It may also be brushed to give a fuller effect. Combine it with another, stronger yarn to give it even more strength.
