The Reason Behind a 5/8" Seam Allowance in Commercial Sewing Patterns
When it comes to sewing garments, precision and accuracy are essential for achieving a professional-looking end product. One crucial element in sewing construction is the seam allowance, which refers to the amount of fabric left beyond the seam line. In commercial sewing patterns, it is standard practice to include a 5/8" seam allowance.
But have you ever wondered why this particular measurement is so commonly used?
In this blog, we will explore the reasons behind the 5/8" seam allowance in commercial sewing patterns.
1. Room for Alterations
One of the primary reasons for including a generous seam allowance is to accommodate alterations. When sewing a garment, it's important to have room for adjustments such as letting out or taking in seams to ensure a perfect fit. A 5/8" seam allowance allows for such modifications without compromising the overall integrity of the garment.
2. Professional Finishing
A larger seam allowance provides the opportunity for cleaner and neater finishing. It allows for graded seams, where different layers of fabric are reduced in width, creating a more even and smooth appearance. Additionally, the additional fabric allows for hemming and seam finishes such as French seams or bound edges, giving the garment a polished and professional look.
3. Reinforcement and Durability
Another advantage of a wider seam allowance is the added strength and durability it offers to the garment. Seams are subjected to stress during wear, and wider allowances help distribute this stress and prevent seam failure. When constructing garments, particularly those made from heavier fabrics or with more substantial seams like outerwear or tailored pieces, a 5/8" seam allowance can provide the necessary reinforcement for a longer-lasting garment.
4. Precision and Fit Adjustment
Sewing patterns are created to fit a certain range of body sizes, but individual bodies can vary significantly. With a 5/8" seam allowance, sewists have more control in achieving the desired fit. This extra fabric allows for easier adjustments, such as letting out or taking in seams as needed to customize the garment to individual body measurements. The wider seam allowance also allows for the use of basting stitches or tailor tacks, which can aid in fitting adjustments before permanently sewing the seams.
5. The Significance of the 5/8" Seam Allowance in Sewing Patterns
The ubiquitous use of a 5/8" seam allowance is not arbitrary; rather, it serves a multifaceted purpose in the pursuit of creating impeccably crafted garments. Beyond accommodating alterations for a perfect fit, this generous allowance allows for a professional finishing touch by enabling graded seams, intricate seam finishes, and overall neater presentation. Moreover, it contributes to the longevity of garments.
The 5/8" seam allowance emerges not only as a practical necessity but as a thoughtful design choice that enhances both the aesthetic and functional aspects of the sewing process.
