The aim of this study is for presenting a new trend for designing of knit wear and searching for the new possibility of the originality and formativeness by mixing & applying the "Knit and Felt" as a mixing technique of knit. In the studying method, we have collected the literatures and photographs of above study around the fashion collections published and surveyed & analyzed them on the basis of the theory. We have manufactured 3 suits of knit wear applying the image of flower with the mixing techniques between Thread Lace technique and Felt of knit on this foundation. The results from the manufacturing the suits of this study are as follows: The first, the weave manufactured with the knit by hand is set free comparatively for the each part because the composed thread is made of a loop. But the weave makes new materials by combining the felt of wool with the nature of easily changing by an external force. We could confirm that the mixing technique of the knit and the felt makes a dual structure and it can express the unique feel of material surface. The second, we have known that the wool can be expressed effectively the image of water painting by applying the Needle Felt technique and can remake the image and differentiation of materials with the decorative effect of the wool. The third, We have known that felt has a resilience but has a weak point which is not able to bear up against a seal and abrasion in order to be used a textile. In spite of this, we could confirm that it is effective to express the decorations by making a ruffle without any sewing after increasing the edge of the textile felt with the mixing technique of a knit and a felt on this study.
