Do You Cut Interfacing With Seam Allowance?

This topic is of utmost importance to anyone pursuing sewing projects, as understanding the correct way to handle interfacing can greatly impact the final outcome of your garments or crafts.

Crafted from 100% core-spun polyester, this thread is specifically designed for use with sergers, overlock machines, and coverlock machines, such as the popular Janome CoverPro family. With the right tools and knowledge, you can confidently tackle any sewing project with precision and finesse. So let's dive deeper into the world of interfacing and uncover the secrets to achieving professional results.

Should I Cut Interfacing With Fabric Scissors?

When it comes to cutting interfacing, there are a few factors to consider. One question that often arises is whether or not it’s necessary to cut interfacing with fabric scissors. The answer to this question is largely a matter of personal preference. Others may find that regular scissors work just fine for cutting interfacing.

Another factor to consider is the type of interfacing you’re working with. Some interfacings may be more delicate or prone to fraying than others. In these cases, using fabric scissors may be beneficial.

It’s important to note that regardless of the type of scissors you choose to use, it’s always a good idea to make sure they’re sharp. Dull scissors can make it difficult to cut cleanly and may cause the fabric or interfacing to fray.

In addition to the type of scissors you use, it’s also important to pay attention to the seam allowance when cutting interfacing. Some patterns may include a seam allowance for the interfacing, while others may not. If the pattern doesn’t include a seam allowance for the interfacing, it’s generally a good idea to cut it slightly smaller than the corresponding pattern piece. This will help to ensure that the interfacing doesn’t extend beyond the seam lines when it’s applied.

By taking these factors into consideration, you can achieve clean and professional results with your interfacing application.

How to Properly Care for and Maintain the Sharpness of Your Fabric Scissors

  • Store your fabric scissors in a dedicated container or case to protect the blades from damage.
  • After each use, wipe the blades clean with a soft cloth or tissue to remove any fabric residue.
  • Avoid using your fabric scissors on any materials other than fabric, as this can dull the blades.
  • If you notice your scissors are becoming dull, use a sharpening tool or take them to a professional for sharpening.
  • Always cut with the full length of the blades to prevent uneven wear.
  • Avoid dropping or mishandling your fabric scissors, as this can cause the blades to become misaligned or damaged.
  • Keep your fabric scissors away from moisture and humidity, as this can lead to rusting.
  • Don’t use your fabric scissors to cut paper or any other non-fabric materials, as this can seriously dull the blades.
  • When not in use, always store your fabric scissors in a safe and secure place to prevent accidents.
  • Regularly oil the pivot point of your fabric scissors to ensure smooth cutting action.

When it comes to sewing, one of the fundamental rules to remember is the seam allowance. This refers to the additional fabric that’s left beyond the stitching line when two pieces of fabric are joined together. This allowance ensures that the seam is secure and prevents fraying. However, achieving the perfect seam allowance can be challenging without the right thread. That’s where Madeira Aerolock Premium Serger thread comes in. This top-quality thread is made of 100% core-spun polyester, specifically designed for sergers and overlock machines. With it’s durability and reliability, it’s the ideal choice for projects that require frequent washing or strain. Whether you’re working with the Janome CoverPro family or any other coverlock machine, this thread is guaranteed to provide you with lasting results.

What Is the General Rule for a Seam Allowance?

When it comes to sewing projects, one of the most important considerations is the seam allowance. It’s a crucial element in ensuring that the final sewn piece fits properly and is structurally sound.

The general rule for a seam allowance is to leave a width of about ⅝ inch to 1 inch. This allows for enough room to sew the pieces together without compromising the integrity of the seam.

For example, garments often require a larger seam allowance to allow for fitting adjustments and alterations. On the other hand, smaller projects like bags or accessories may only require a narrow seam allowance.

When it comes to interfacing, the general rule is to cut it without seam allowance. Interfacing is a stabilizing material that’s used to reinforce certain areas of a garment, such as collars, cuffs, or waistbands. Cutting it without seam allowance ensures that it won’t add bulk to the finished garment and that it will lay flat against the fabric.
