Wisper is on special from $6.25 per card.
"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.
(4 strands on 13-14 count canvas, 2 strands on 18 count and 1 strand on 22 count)"
