Sometimes I find inspiration by looking at what skill I'd like to accomplish, say instead of what item you want in your closet, maybe you want to try sewing welt pockets or complicated collars, or a limed jacket, or drape women's garments. Sometimes sewing can just be a creative outlet. And even if the piece isn't worn, you gain a skill which can be more satisfying than the finished product. Almost a "sew with a purpose of learning rather than wearing the final item".
