63f40633-ce01-4ba1-ab05-aad6b8803260I love teaching these processesIt’s a core part of my practice and my work in building resilient communities, a creative social practice and supporting sustainable living through handcrafts, making and mindfulness or “mendfulness”.

You can book me for an hour illustrated talk, a day workshop or week-long retreat, from tots to teachers, of all ages and abilities.

the day was wonderful, I loved it. You are an inspiration and a lovely teacher.. I used my news inks today on a sample  piece and they are beautiful

To prepare for a workshop:
All materials and recycled/organic fabrics are supplied for you, but it’s a good idea to bring your own preferred gloves, a basic sewing and art kit with things like scissors, pins, needle and thread, pencils, ruler, brushes, anything you like to use in your own work. Also some plastic bags to take wet work home in. For dye classes, you may bring your own small pre-washed items to transform: such as napkins, tee shirt, pillow case, a summer dress, linen trousers, scarves, a shopping bag or a table runner. The items don’t have to be white, in fact, some of the most interesting transformations happen on items originally with a print or other colour. Loved, gently used or stained items are also a great choice. Check the labels of the items to make sure they are made from natural fibres such as cotton, bamboo, hemp, wool, linen, viscose or silk.
You need to wear clothing that you do not mind getting a drip or two of dye on!

A parent of a participant on a young people (Criw Celf) project wrote to me:

My son ..enjoyed the half term project with Cath Lewis enormously. She’s a great teacher who engaged and encouraged him to create some lovely work. He came home every evening talking about the activities of the group and what he’d learnt. He was inspired to work hard on his book, which he enjoyed making from recycled materials, and is

already using his walnut ink for his GCSE work as well as making some of his own.

He found the experience of working with artists inspiring and it was lovely for me to see him come home buzzing with ideas and he’s looking forward to putting more of his ideas into practice.

This project was a wonderful opportunity for him and I’m delighted that he was given that opportunity and was able to take advantage of it.

He’s looking forward to the next project / workshop!’

If you would like to book a group workshop I can travel to your venue or you can come to the workshop in Cardiff. I supply all equipment and materials for a workshop tailored to your ages, interests and needs.
