Whether you are working with a pattern or not, our technical files have been designed to enhance and clarify the making of certain models and garment parts. With this file, earn how to make a dropped sleeve with an elbow seam (for a jeans jacket base). The process is made easier by the file’s detailed instructions and explicit sketches that need to be followed step by step and that will lead to a top quality result in the predefined size of your choice. By definition, a dropped sleeve is a long sleeve that falls onto the arm and ends, in this example, by an added cuff. This sleeve also has an elbow seam, which shapes the sleeve and absorbs some of the excess value. The sleeve-end remains fairly classical with a vent for the hand to pass through. The hem of the sleeve has been simplified to facilitate assembly with the cuff. The cuff base pattern is constructed straight (with no shaping). Other transformations of this base are possible. For complete this construction, you can work with the following file: The technical file of the jeans jacket.
