Check the measurements on the pattern carefully to ensure the apron is the right size, as vintage patterns are typically based on smaller measurements than modern sizes. When purchasing fabric for the project, calculate the necessary yardage using modern fabric width, rather than the smaller fabric widths of previous decades. Use tailor's tacks to transfer the pattern onto the fabric, and refer to the pattern to determine the seam allowance.
Become familiar with traditional, and often disused, terms that are included on vintage sewing patterns before sewing the apron. For example, the term "plaits" refers to the modern knife pleat. Additionally, some vintage patterns have symbol-based instructions, such as circles or triangles, rather than word-based instructions.
Become familiar with the meanings of the symbols before sewing the pattern. Read the pattern carefully before sewing the seams, as standard seam allowances didn't become common until after the 1940s. To ensure you understand the pattern, make a practice muslin from inexpensive fabric before sewing the apron.
Use the practice muslin to adjust the pattern or sewing techniques as needed. To create an apron that has an authentic appearance, use traditional sewing techniques, such as including bias binding on the garment. To maintain the authentic appearance of the apron, use fabric that features traditional patterns, such as floral fabric paired with dot-patterned trim.
