Buy the ZW Block Pant sewing pattern from Birgitta Helmersson. This is a zero waste pattern which comes in 10 sizes. It has an attached waistband with inserted elastic and front pleats for a slightly tailored look. There is a feature seam line on the back legs. The side seams sit slightly to the front. There are concealed in-seam pockets at the front and patch pockets at the back. This pattern also comes with a hack option: a skirt with patch pockets and an elasticated waist.


Zero waste pattern cutting is a bit like a puzzle. It is a method of pattern drafting where you utilise a length of fabric end to end by strategically planning your pattern pieces so that everything is used. This pattern is ‘paperless’ meaning that no large pattern pieces are required. Instead of using full scale paper pattern pieces, you draw your pattern directly onto your fabric with the aid of a cutting plan and small templates. This method has several advantages:

1. More flexibility. This method allows for easy changes such as using different fabric widths and making simple fit and design changes yourself. Using patterns that fit into a zero waste square or rectangular block is a very efficient way to work. It means that it is easier to patchwork together remnants or use leftover fabrics you already have lying around.

2. An easy way to learn to self draft your own patterns. Working this way will help you to start building a toolbox of skills, and you will learn an alternative method of self drafting which is super easy for beginners to understand.

3. Less fabric and paper waste!

NOTE: With the exception of some small templates, this zero waste pattern has no pattern pieces. You will draw the pattern directly onto your fabric by following the step-by-step instructions in the pattern booklet and using small templates which you can print easily on your home printer.
