Birgitta Helmersson - Zero Waste Block Trousers and Skirt - PDF Pattern

  • Make a Selection

Please note: This PDF sewing pattern uses zero waste pattern cutting and comprises of instructions to draw shapes directly onto your fabric. With the exception of some small templates, there are no pattern pieces to print out and tape together.

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 printing of large pattern pieces is required. Instead of using full scale paper patterns, you draw your pattern pieces directly onto your fabric with the aid of a cutting plan and small templates.

This is a zero waste pattern which comes in 10 sizes, XS-6XL. 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, this placement is higher or lower on the leg depending on your chosen size. The side seams sit slightly into the front pant and there are concealed in-seam pockets at the front and patch pockets at the back. This pattern comes with one hack, a skirt with patch pockets and an elasticated waist.
