When I saw the drinking straw pin I thought: ‘Oh yes, I want!’ ;-)
It is quite easy: I took two different coloured drinking straws, cut them (veeery carefully!) into spirals with an X-acto knife und knotted them (not too firm) together.
This way my little ball stays in form without glue, sewing or the like.
I wanted to cut them first with scissors but I got ugly edges, the cut must be made with a really sharp cutting tool.
I find it cute as well as jewelry as well as tree ornament ;-)
