ok..i tried to make a tute.
but i hope you understand what i mean, because my english is not that good.
i think the best you can do is find a basic skirt for your measurements, because i dont know how i can explain how to draw the complete skirt in your own size.
this is how the basic skirt will look like.
start drawing the pink lines on a new piece of paper, then hold your pencil still above the star, and move your paper till the two sides get together.
i have a pic to explain.
the black lines are the original ones, the blue lines are the same lines when you fold the pink and blue lines together.
then draw the red line from pink to blue.
and thats your new basic skirt.
draw the new basic skirt on a new piece of paper, draw the whole front.
now you can draw the other lines where you want them to be.
and now you can draw the seperate pieces.
*the fabric for the holes.(you have to take the fabric on a foldline)
do the same for the backskirt.
for the side strips with holes you need to take the front and backparts together.(also these on a foldline.)
*sew the strips for the holes together, and turn it inside out.
put the holes in it.
*sew the side front and side backs together.
*sew the hole strips to the sideskirts.
*sew the sides to the front with the front holestrips between them.
*sew the back to the sides.
*sew the zipper on the middle back.
now we need the layers under the basicskirt.
oh you need to make seems, but i think thats obvious.
i hope you know how to make one for yourself now.
let me hear when you have questions about it.
and post pics when its ready.
