Ooh, Rhyb - I have the side snapping bumble bee (& caterpillar) and they are fabulous, DH's favourites too.

Heather - I tried to lanolise my one wool cover (I hate wool soo wish I'd just stuck with fleece/minky) once and sucked at it ended up with lanolin plastered to my fingers and the bottom of my sink but not dissolving - don't think water was hot enough? You're supposed to get a pea sized bit of lanolin and dissolve it in a tiny amount of hot water and then fill the rest with cold water and leave it to soak.
