Abstract: Disclosed are a support sheet for folding, fixing and packing a suit of collared clothes and a method of packing the clothes making use of the support sheet. The support sheet is made of a sheet of paper or a plastic and is provided with a number of slits for fixing respective parts of the clothes to the support sheet in a suitably folded state, thus eliminating the use of clips and, particularly, at least needles which may injure the user's finger and damage the clothes during packing and unpacking, so as to shorten the time and reduce the cost of packing work and to enable the user to easily separate the clothes from the support sheet, as well as to reduce the amount of packing material to be wasted after the use.
