Took some inspiration from some over on the 'cartridges out' thread.

Ordered a plain case from Amazon (less than a tenner) and butchered the insides to make some sections for storing my (somewhat cut-price) carts. Not only does it look better than having them all over the place but it also serves to stop my two year old asking why we have "lots, lots, lots". Preceding to pick them up with me approaching him as if he's carrying a loaded gun (as quickly as possible without scaring him into an abrupt movement . . . ).

Lined with a rather fetching (if I may say so myself) lilac handkerchief.

Happy with that.
