Tamago sushi, please

[juanitatortilla.livejournal.com]

Hello, hello.
this is my SECOND crochet project
created out of impulse.
(I am a crochet newbie.)

The 'rice' is stuffed with yarn snippets from past knitting projects.
I have yet to think of a purpose for this Tamago;
either use this as a pin cushion, or attach a magnet on it!
Any ideas?
