This scarf is fully reversible with a great springy texture.
A 200g ball of wool makes a nice size scarf. I have made them smaller and also with 400g! As you start with 2 stitches and are always increasing, the end is when you decide.
The instructions are for working with 2 yarns, A and B, if you want to use plain or different colours.
I use both ends of one ball of wool, although it can get in a tangle.
It does works just as well with just one yarn of marble chunky as the colours shade so nicely.
