Those empty cardboard rolls are super for storing cables, extension and electrical cords, Just fold the cords in an elongated shape (like an 8, without the crossover) and inset it in the empty roll, then write its description on the ouside such as length or what utensil or device it belongs to, Christmas tree lights, etc. Eliminates tangles which are bad for cords. PS - Scott tubes are best because they're strongest.
