Since they moved to her new house, Rocio is restless and scared. That house is so big! Actually, she is always with her mum, as if they were sewn together. However her mother, who is not a dressmaker but is very good with a pair of scissor and some thread, has got a plan ... She will make her a very special dress, and thanks to some colour threads, she will show Rocio that even if they are not in the same room, they can always be together. This is a very loving book which helps children to confront the fear of loneliness and also helps to make them see that emotional attachment is stronger than physical proximity.
