To readily form a complicated pattern on the surface of a base material for small articles made of cloth or leather or of clothes without occurrence of defective product.

At first, a pattern 13 is formed on one surface of a hot-melt film 12 by means of a variety of techniques [see figures (a) and (b)]. This hot-melt film 12 is preferably used, as the release paper is laminated, to form the pattern. Only the needed part of the pattern is cut out of the hot-melt film 12, the release paper 11 is peeled off, the hot-melt film 12 is placed on the base material 14, as the face not forming the pattern is turned to the surface of the base material 14 such as cloth [see figure (c)] and heated with a roller press or an iron. Then, the hot-melt film 12 melts, impregnates into the base material 14 to fix the pattern 13 to the base material [see figure (d)]. Since the pattern is indirectly formed on the base material 14, the base material itself such as fabric material or clothes never becomes defective even when the pattern formation fails.
