I'd really like to make one of these for ds for Christmas - anyone got any fab ideas or also tips on where to buy things the cheapest?
So far I've thought of the following but it's budget dependent
Small briefcase? 2nd hand?
Magnifying glass - got
Invisible ink pen
Spy glasses
Cardboard covered in newspaper with eyeholes cut out
Some kind of mini telescope
Finger print ink pad
Notebook
Binoculars
Moustache / moustache tattoos
Torch
?????
Ds is turning 7 at Christmas
