Interlacing colours
Let’s get started — twining (or twisted ‘header’) in place, you can begin to weave, using the comb to ‘knock down’ your work against the twining as you proceed. The knocking down process is necessary to keep your work as neat and compact as possible.
According to your chosen design, you might be planning on using multiple colours in one area — working them side by side. This is where interlacing comes in useful. I mention the use of a needle as a ‘third’ alternative for filling gaps — this should be done with yarn and not just a normal thread of course.
