“It isn’t really double knitting! – I can’t separate the layers!”
This is one of the most common comments I hear from muggle* knitters as they try to separate the layers of two-colour patterned fabric. *A muggle knitter is one is as yet not fully aware of the mysteries and marvels that the parallel universe of DK offers!
You can work DK with entirely separate layers, however, this can only be achieved in single colour DK when making tubes or an open-at-one-edge fabric.
To achieve unconnected layers if using two colours, each one must be used only on one side. The edges can be open or connected.
Whenever you have two-colour DK with a pattern you will join the fabrics at the sides of each colour block. However the middle of each colour block area will be separate – this is what allows the bubbles in my Bubbles Scarf to be stuffed.
I often use the connection of the layers to secure the fabrics together. In my Cape Spear Blanket the area between the big motifs would be entirely unconnected and probably baggy if I didn’t add the bands of chequered turquoise/lime across the width of the design.
For further arcana for the initiated, there is my DK Club which offers an ever expanding selection of clips relating to DK
The same swatch is shown opened up on the right, the vertical pockets are unconnected except at the sides. To create horizontal closures a threaded /quilted colour change is needed. (More another day….)
