When I saw the picture I thought: ‘Wristwarmers for skeins?’ ;-)
No, it is a skein holder to prevent the skein from unraveling and rolling around when you knit it from the center.
By the way, I have presented before how to wind a center pull yarn ball :)

Center Pull Yarn Ball
If you have yarns with colour changes you won’t know how the knitted item will look.
The little programm for the planned pooling for knitting helps you to get an idea, you only have to fill in the number of stitches per row and per colour and if you knit in rows or in rounds.
