Thanks, that's super helpful!The problem is the width. The length of a standard A5 notebook is fine but the width is generally just over 14.5cm on a standard A5 notebook. You ideally need a notebook around 13cm wide to fit the notebook cover. Moleskin do one, their classic soft cover notebook which is 21cm x 13cm & this fits perfectly. You can pick them up on Amazon fairly reasonable around £15 & they come in lots of colours. Hope this helps😊
