12oz Organic Cotton

The Cloth

A classic utility twill made from organic cotton. While the cloth is fairly heavy at 12oz/410gsm, it still has a soft brushed feel to it as it’s been washed and emerised at the mill. An ideal cloth for jackets, coats, bags, dungarees, and trousers that require some structure. 

Production & Certification

Cotton makes up over half of the fibre used in clothing and textile production worldwide. It has a long history and is a favourite amongst makers for its flexibility and durability. The fibre starts life as a soft, fluffy staple fibre that grows in a boll (protective case) around the seeds of the cotton plants.

Over 60% of the world’s cotton is grown and produced in developing countries and provides a livelihood for over 100 million farmers. But intensive farming methods are often used, such as overusing water and pesticides, and those methods threaten the ecosystems cotton depends on. We therefore look for mills that are Fairtrade or Organic. Organic cotton is cotton that is produced and certified to organic agricultural standards and so sustains the health of soils, ecosystems, and people by using natural processes. Organic cotton farming does not permit using toxic chemicals or genetically modified crops. Instead it combines tradition, innovation, and science to benefit the shared environment.

Made in Turkey, our 12oz organic sanded twill range is 100% Organic Cotton that is OEKO-Tex 100 certified and ISO 9001 & ISO 14001 certified. We work with a mill in Turkey focused on investing in eco solutions to reduce emissions as much as possible. In 2020, the mill invested in a A++++ energy efficient air conditioning and heating system which has reduced their energy usage by 50.2% the following year. They’ve also planted 1000 Red Pine trees to offset a portion of their CO2 emissions. In 2021, the mill started to harvest rain water with the aim of only using rain water in their production – the rain water is recycled and re-used in their dye plants. 


Suitable Patterns


How to sew 12oz organic sanded twill

  • Our 12oz Organic Sanded Twill range behaves much like the 8oz. It's quite heavy-weight and sturdy, so we recommend clipping and layering your seams to reduce bulk where possible. 
  • We opt for Extra Strong Thread (rather than Topstitching thread) when topstitching. Remember to increase your stitch length (typically between 3-4). 
  • We would recomend using a size 12-14 needle with this cloth.
  • We strongly recommend ironing throughout your project and using lots of steam. Becuase of the emerised finish we'd also recommend using a press cloth. 



Fabric Care

How to pre-wash 12oz Organic Sanded Twill

We recommend pre-washing twill on its own at 30 degrees with a non-bio detergent, delicate cycle with a low spin. When washing heavy-weight cloth like denim or twill in the washing machine, putting one large piece of cloth in the washing machine can sometimes lead to white creases in the fabric as it does not have enough room to move around. It is often helpful to sink your fabric into water beforehand and let it fully absorb before placing it in the washing machine. As well, if you can, we recommend breaking up your fabric into smaller pieces.
If any white creases have developed, iron on a medium heat whilst damp.

How to wash 12oz Organic Sanded Twill

When you have made the garment we would recommend washing it inside out, using similar settings to the ones used when pre-washed. We would recommend delicate 30 degree cycle with a low spin, using non-bio detergent. 

How to dry 12oz organic sanded twill

This cloth can be tumble dried on a low heat. Do not dry in direct sunlight as this can bleach the fabric.
