A yarn ghost is a tassel with a head. You wrap yarn around a piece of cardboard, tie the bundle at one end, stuff the top to round it out, and cut the bottom loops open. That is the entire technique, and it takes about five minutes per ghost once you have made one.
Krysta Meeker of The Meekers makes hers with white worsted yarn and black fabric puff paint for the eyes. There is no sewing, no glue gun and nothing that needs to set overnight apart from the paint.
What decides how the ghost looks
Two things. The height of your cardboard sets the length of the ghost, and the number of wraps sets how full it is. A taller rectangle with the same number of wraps gives you a long, wispy ghost. A short rectangle heavily wrapped gives you a dense, stubby one. Cut a couple of different templates and hang a mix on the same string.
The stuffing is not optional
It is tempting to skip the tissue in the head, and the result is always the same: the top flattens out and the whole thing hangs like a mop. A ball of Kleenex, tissue paper or a cotton ball is what holds the round shape that makes it read as a ghost at a glance.
Eyes without paint
Puff paint gives the raised, slightly glossy eye, but it needs a couple of hours to dry. Small googly eyes glued on, or circles cut from black felt or cardstock, both work and let you hang the garland the same afternoon.
