A skirt for Barbie, based on a costume worn by ABBA.

Look for pattern by number at http://www.stickatillbarbie.se.
The website is in English & Swedish, but patterns are available in several languages.

On the website you’ll find the patterns listed on the left, by number, grouped on pages.
Accessories like hats, scarves or bags are listed in the accessory section, below in the left column.
Click on numbers to open a page, look for the numbered image, then for the link to the desired language below it (clicking on the image will only enlarge it).

This pattern comes in a .doc file.

The pattern calls for 2 sets of dpn (you can also use two circular needles and magic loop). To make a ruffle you have to work a separate piece in the round while the skirt is still in progress, then in joining round you knit together one stitch from the ruffle (still on the needle) and one stitch from the skirt.

Gauge is not given in the pattern but you can find it in the yarn section of the site.
