Lucet: Encasing

Start with two colours. BUT only do the lucetting with one colour.

The other colour will stay in the middle. Dont't wrap it around

All you do, is when you turn your lucet, the other colour gets flipped to the other side while staying in the middle. Just ignore it.

When you decide to change colour, you pick up the other colour.

In this picture i will do one more blue hook. 

Then after my lucet turn, I will leave the blue one in the middle again.

So I will have one round with a blue one at the bottom and a white on top.

And then its only white again.

This is what it looks like when you do a couple of blue ones in a row and then switch to white.
