hello starlover, not quite a laundry basket but what i did was to convert a pillowcase into a laundry bag for ds by sewing/inserting a cord around the rim. use an animal themed pillowcase perhaps? also, got a real cheapo 50p hook from the local shop and stuck a tractor tom sticker on it and stuck it on ds room wall to hang the laundry bag from and he thinks it's christmas all over again
Saw some of those pop-up ones in Homebase yesterday (for toys or laundry) - they fold away flat after use. They had Spiderman and Barbie, then their own range, spaceships and jungle I think. Argos has similar. Hope that helps.
Also, I second Ikea for simple storage. We've got a fold away laundry basket for £2.50! Not all that stylish, but washable and folds flat.
