to paint in large letters in tippex...

[bachsingingmum]

on DD's new umbrella "Belongs to [DD's name]" - on the fabric part, on the outside.

She's had two umbrellas stolen from the top of the lockers at school in the last two days!

i would just get her a coat with a hood

Give her a plastic bag so she can put it inside her locker?

Put a booby trap of something horrible inside so that when the thief opens it they get a surprise

@ ledkr. BIG hairy spider should do it

Permenant market would do it better, they could chip the tipex off!

YANBU though.

write her name on each section!

How about a pesonalised umberella?

Thanks for the ideas. As a temporary measure while I source a spider supply I've gone for the plastic bag in the locker solution. Why didn't I think of that!
