Remove the measuring tape only 2 measurements:

1. FROM the waist size. Measured exactly on the waist line.

2. DI — the length of the product. Measured from the waist line at the intended bottom of the skirt.

When taking measurements the tape should not SAG and be very tight. For ease of measuring the length of the skirt you can tie the waist band

Record the measurement results.
How to sew a skirt bell
Pattern skirts-the bell is a structure consisting of two semicircles, a smaller radius R1 – a waist circumference of greater radius R2 – skirt length + the distance from the edge to the waist line.

So, do the necessary calculations. We first calculate the radius of the smaller semicircle R1. According to the formula, the circumference L = 2nr. As bell skirt is a half circle, so in our case, with the known measure waist girth () formula looks like this:

2ОТ = 2nr1,

reducing the numbers and calculated the radius.

The result:

R1 = a/π.

where π is known to the digit in mathematics the ratio of the lengths of the circumference and diameter and equal 3,14159265...

Conclusion: the radius of the smaller circle pattern of the skirt is equal to the volume of the waist divided by the number π.

The radius of the larger circle is calculated simply: the skirt length (DI) added to the value of the smaller radius R1.
Now, when finished all the calculations, build the pattern directly on the fabric. If your fabric does not have a clear direction of the pile or pattern, we can simplify the task and to sew a skirt with only one seam. To do this, when cutting fold the fabric in half across the width of the cloth so that the distance on both sides of the rectangle were no less than R1 + R2 + ~ 7cm (one side seam and hem the bottom – both sides).

From the edge of the fabric put a ~ 2cm and draw a cut along the entire edge. This will be the seam line and zipper at the skirt. The upper point at the intersection of the fold of the fabric and the seam will call point O.
From the point Of put in both sides 2 cut equal to R1 and R1 + R2 and mark them with tailor chalk. The point O is the center of the arc, which put the same segments at a small distance from each other in the form of a dotted line. Do it gently, without moving the measuring tape from the center. Connect lines marked by smooth arcs. Now, stepping back from the arc of the larger radius guide dotted line at a distance of ~ 5cm down from it. Better to do it, using the cm and the center of the arc. It will be a line for bending of the bottom of the skirt. From the smaller arc up put ~ 1-1. 5 cm and also draw a dotted line. This will be the seam allowance on waist line for protecive zone.

Do not forget that the remaining tissue will have to find the belt in the direction of the grain lines. Estimate in advance the location on the fabric. Belt size: 2 width, because it should be to sew folded in half. The length of the belt equal to the amount of your waist + 0.5-1cm free fit + 4-6cm for a button closure or a hook.

Put the obtained distances on the fabric and draw a line of the rectangle. Don't forget to set aside a dotted line the seam of the belt width and along the length of 1-1,5 cm on both sides.

Raceskroite the details of the skirt with scissors strictly by the dotted lines of the seam.

Sew the seam of the skirt at the line of primaqiune lightning. Seam Ratatouille iron "vrazbezhku". Vsheyte zipper.
Adhesive fabric for corsages cut a strip equal to twice the folded belt. Priutyuzhte it to the underside of the belt , and the belt will astrocyte laterally and turn there. Fold the waistband in half and iron.
Before pritachivajut the waist to the skirt is slightly pripasayte her waist with a wide seam with stitch. You can also lay hand straight seam with a needle and gently pull the thread. Skirt pripojeni waist sits perfectly on the figure. Baste the front side belt (the one to which the interlining is glued to the skirt and sew the seam. Avoid folds and Zamyatin on line. Pristrochite inner side of the belt by any suitable fabric for this method.
Will pripasayte edge hem skirt hand stitch or machine stitch wide. Baste the hem inside out and priutyuzhte iron. Check for kinked it somewhere in the bottom line. Now you can sew the hem by any suitable method (manually hidden seam, machine stitching a straight seam or Poggibonsi).

Make a loop at the waistband, sew a button.
