Circle skirt construction is pretty easy you just need to know a little bit of geometry. One simple formula how to calculate the radius knowing the length of a circle is all the math you have to know.
Sewing is not complicated too. It requires few pieces and basic techniques, making it is a good exercise for beginners. If this is your first time I would advise you to begin with a paper pattern. For experienced sewers this step can be skipped, you are welcome to do the markings straight on the fabric.
Circle skirt construction math.
To make this pattern you will need only two measurements – waist girth and the length of your skirt. This will allow you to calculate the radius of the circle.
Often the design calls for less folds then the full circle gives. In this case a circle skirt is made not in 360°, but less – 270°, 180° or 90°, depending on how many folds is needed. On the other hand for abundant fullness a circle skirt can be doubled – two circle skirts sewn together (don’t forget to halve the waist girth of each).
How to calculate the waist radius for each type of circle skirt.
- Full circle skirt (360°)
- 3/4 circle skirt (270°)
- Half circle skirt (180°)
- Quarter circle skirt (90°)
Now, when you know how to make a pattern, I would like to give just a few points on laying it out and cutting fabric for each type of circle skirt. Folding the fabric is the key:
For the full circle fold the fabric twice. If the fabric is wide enough you can make a skirt without seams. If not, there are alternative ways of cutting your fabric.
- For the 3/4 circle fabric is folded the same way as for the full circle. The extra quarter is removed after the skirt is cut, leaving sufficient seam allowances.
- Half circle skirt pattern needs only one fold of fabric.
- Quarter circle skirt pattern is usually layered on a straight grain, but can be cut on bias for the more tailored look.
Cutting the fabric.
Lightweight woven fabrics are the most common choice for this skirt. The soft folds along the hem without much bulk around the waist line characterizes this skirt fit. It can be made in any length but may be limited by the width of the fabric. However there are ways around this problem. If your fabric is not wide enough, you can make your circle with two halves (don’t forget the seam allowances). If this is not an option you may consider a 6, 8 or 10-wedge skirt, it will give you a similar look.
Finishing the waistline.
A circle skirt is usually finished with a waist band. The width and style of it is entirely up to you. Typical methods include:
Comfortable to wear and simple to make; it often used in kids clothing. One thing you should remember though! Leave enough ease along the waist, otherwise how will you put it on? As a general rule add 15-20cm to your waist girth measurement before calculating the radius.
Gives the skirt a more tailored, “grown-up” look. If you go with a welted or exposed zipper, the skirt doesn’t need seams at all.
Waistbands are not the only way to finish a circle skirt. You can cut a facing using the top of your skirt as a guide.With this method you can use the centered zipper technique, or go with the hidden zipper method.
Hemming your circle skirt.
The circle skirt has a curved hem, this limits the methods it can be finished with. There are however quite a few hemming techniques you can rely on.
There is one problem with the circle skirt that occurs most often – uneven hemline. This happens because the fabric stenches significantly on bias and doesn’t have any stretch on a straight grain. The parts of the skirt cut on straight grain will be the most stable, those that fall onto the cross grain can warp a far bit. The portion of the skirt that falls on bias will be the least reliable and may stretch after a wash or two. It all depends on the fabric! If you suspect that this will happen to your skirt, I can recommend a small trick. Finish the waistline but leave the hem unfinished. Wet the skirt throughout, peg at the waist and drip-dry it, letting the fibers settle into shape. When the skirt is dry, carefully measure the desired length. Mark and cut the excess fabric where it stretched, evening out the hem. That should do the trick. Your skirt should be the same length now and won’t give you trouble later. Finish the hemline in any way you want.
