Hi Keeo-
here is the tutorial I use...
http://freshlypicked.blogspot.com/20...-tutorial.html
For the skirt, I just cut the pillowcase to the length I wanted it, leaving enough for a 1 inch top hem (so 1.5 inches longer than I want the skirt to be). Since it was going to be see through, I took the top half of the pillowcase, and cut the top seam off, hemmed one edge and sewed it to the top edge of the "skirt" piece, then I folded both hems down 1/2 half inche and ironed them, then folded it again the 1 inch, and sewed around leaving a hole to insert elastic- the elastic is the waist plus 1/2 inch. insert the elastic and sew it to itself, then sew the skirt shut (hope that makes sense)
the concept is similar to this but you start with it already hemmed and in a circle.
Be happy to offer any other help you might need-
