Way 2
You will need the following.
At least 7 yards of a light weight material. It needs to be at least a few inches wider then your inseam. (which shouldnt be an issue because most fabric is sold at about 48 inches wide or more)
(7 yards will get you an 11 yard skirt)
1 Sewing Machine and thread
or
1 sewing needle, thread, and a crap-ton of time.
Sewing Pins help, but arnt essential.
Scissors
A thick, sturdy elastic
Large Safety Pin (For threading elastic)
Measuring tape.
The ability to measure 1 yard, and 3 yards.
Cruddy Fabric or Muslin to make a patter, Optional
Take the following measurement of yourself.
-Inseam (It's from your crotch (I hate that word.) to your ankle. Some people measure form hip to ankle.)
-Add on 4 inches.
If you want to make a pattern from muslin, now would be the time. (See pic below) If you feel confident, go ahead and just measure it out on the fabric it's self, and then use the first piece you cut out as your pattern piece.
-Measure 1 yard across the top.
-Find the center at 1.5ft. then measure strait down the length or your inseam plus 4 inches.
-Mark the fabric
-Measure 1.5 yards on either side of the mark.
-From the corners of the 1.5y measurement, get your measuring tape, and make an angled line to the top of the pattern.
-Cut out.

Find a nice big space you can lay your material out. Unfold the width.
-What I usualy do, unroll the fabric for a few yards, and then unfold the width and lay it out, leaving the rest of the unrolled fabric in a pile at the end of my work space. When I need more fabric, I give it a pull and a little toss of the matieral. This way it doesnt get tangled.
-After you have piece number 1 cut out, flip it over, it will line up perfectly on the material, and cut out another piece.
-Continue flipping and cutting as shown above. This will give you the best use of the material you have, and will make 7 yards turn into 11. (That's measuring the length at the bottom of the skirt)
(See pic below on how to piece the skirt together.)
-Once you run out of material, take two of the cut out "triangles" and match them top to top, bottom to bottom.
-Pin the pieces together if you so choose.
-Sew the two pieces together.
-Get another "triangle" and add it to the free seam of the two you just put together.
-Continue until you run out of "triangles".
-Make sure you're keeping all the inner seams on side side. (I've had to redo a skirt because I wasnt paying attention.)

-Match the two end pieces together, and sew them together.
- Hem the top of the skirt, enough to feed the elastic through. (About 2.5-3 inches)
-Hem the bottom of the skirt.
-Feed the elastic through the top.
TADA! You have a circle skirt!
Here's my skirt in action...
