Crocheting a toilet roll cover with a doll in the centre is a quick and fun housewarming project for your vintage-loving friends. You probably can’t buy a doll created specifically for the job like you could the past, but I reckon any $2 or reject shop would have an appropriately sized doll. The height of a toilet roll is about 10cm (or 4 inches) so an 18cm (or 7 inch) doll should be fine.
