Fission Knitting: Mary Martin (via Zoom)

Mary Martin is a knitwear designer based in Toronto, Canada who focuses on reversible fabrics. She has developed two reversible techniques: Fission Knitting and Fusion Knitting. Mary will be joining us to teach an introduction to Fission Knitting.

Fission Knitting is a reversible colourwork technique where the fabric is worked with two yarns held in a marl. The design elements are slipped stitches placed on both sides of the fabric. The marl is broken apart to work these stitches. The resultant fabric has a marled middle layer and an overlaid design on each side. It is possible to create a different cabled design on each side of the fabric.

In class you will work a small Fission Knit swatch to learn the most used stitches and cables. The emphasis will be on reading your knitting and applying the 3 Rules of Fission Knitting. You will learn the properties of Fission Knit fabric, why the technique works, managing your yarn and choosing suitable yarn/projects. There is no homework for the class.

Materials Yarn: small amounts of 2 solid coloured contrasting yarn in sock/fingering to DK weights. Smooth/not textured yarn is recommended. Leftovers of sock yarn are perfect. Needles: 4.5mm/ US7 needles for fingering weight yarn; 5.5mm/US9 needles for DK weight yarn. Other: cable needle, removeable stitch marker, hair or regular elastic, small bag (eg. a plastic sandwich bag that holds both balls of yarn) Note: You may use yarns in any colour. 

Mary will stay 15 minutes after class to discuss kits for the fission skills that you learn. We will have them available for purchase. 

From Mary...

"In terms of kits:
I love both Sweet Georgia Tough Love Sock & Dream in Colour Cashmere.  Both work very well for my work.  Solids and tonals are the best options.
I have a series called the Flowing Marls (  It has 3 cowls that increase in difficulty level.  The easiest of these (Flowing River Cowl) is free with a signup to my newsletter and is a great first project.  All 3 cowls have the same yarn requirements so a kit would work for any one of the 3 patterns.
I have several other scarves (Fission Twists, Comet Trails, Fraternal Forever, Genetically Linked, Blockchain).  These ones are all good ones to use the skills taught in class.  They would each use 2 skeins each of 2 colours."
