I wanted the colour blue to really stand out, but at the same time I didn't want it all blue. So I chose a grey, rather thick thread.
This was my first plan. The black at the sides are magnetic beads that I thought would make bit of an interesting addition. But I was not that happy with this as I felt that it did not give the right feel. I wanted more blue colour. So I took a several small beads and sown them into one part of the thread. Then I wanted to add the blue beads that you can see just above the blue heart. However, the holes in the beads were to small for the thread to get through. I tried everything, but then I suddenly decided to try and shred the thread. That worked:
Here you can see both the part where I have sown the small blue beads into the thread, and also the many, many thin threads that make up one large thread. There were really a lot of them, but as you can see on the right hand side of the picture, I was now able to get the blue beads into the thread.
I decided to remove the black, magnetic beads as I felt that they did not fit into the new design.
So the ned result was:
I also made a bracelet to match in colour, and I think that I am in love with the grey thread. It is so soft and supple.
