How Well Does a Double Fold Binder Work on Spandex?

When it comes to enhancing the functionality and aesthetics of spandex materials, the utilization of a double fold binder proves to be highly effective. This innovative accessory ensures impeccable control, durability, and a professional finish for various applications. Whether used in activewear, swimwear, lingerie, or other spandex-based products, this versatile binding technique provides a reliable and aesthetically pleasing solution that meets the highest standards of quality and performance.

Should I Double Fold or Single-Fold for Quilt Binding?

When it comes to quilt binding, one of the primary factors to consider is the level of usage that the quilt will see. For quilts that are purely decorative, such as wall hangings or decorative table runners, using a single-fold binding can be a suitable choice. Single-fold binding is created by folding the binding fabric in half and then sewing it along the raw edge of the quilt.

This type of binding provides added durability and strength, allowing the quilt to withstand regular wear and tear. It helps to secure the raw edges of the quilt, reducing the chances of fraying or coming apart with repeated use.

The extra layers of fabric in the double-fold binding add an extra level of protection for the edges of the quilt, preventing them from fraying or unraveling.

Ultimately, the decision between single-fold and double-fold binding depends on the specific needs and purpose of the quilt.

How to Calculate the Length of Binding Needed for a Quilt

  • Measure the perimeter of your quilt top.
  • Add the length of all sides together to get the total length of binding needed.
  • Choose the width of your binding strips. The standard is 2.5 inches, but you can adjust based on your preference.
  • Calculate the number of binding strips needed by dividing the total length by the width of each strip.
  • If your fabric width isn’t enough, you can sew multiple strips together to create a longer binding.
  • Cut the binding strips according to the needed width and length.
  • Join the strips together at a 45-degree angle to create a continuous binding.
  • Press the seams open for a flatter finish.
  • Fold the binding in half lengthwise, wrong sides together, and press it.
  • Begin attaching the binding to the quilt, aligning the raw edges, and leaving a small tail.
  • Sew the binding in place along the quilt’s edge, using a ΒΌ-inch seam allowance and removing pins as you go.
  • Miter the corners by folding the binding up and away from the quilt and then down to create a neat angled fold.
  • Continue sewing the binding until you reach the starting point, leaving another small tail.
  • Join the ending tail and the starting tail with a diagonal seam, trim the excess, and press the seam open.
  • Finish sewing the binding to the quilt, ensuring the stitches catch both the front and back of the binding.
  • Trim any excess binding and press the entire binding away from the quilt.
  • Finally, fold the binding over to the back of the quilt and hand stitch it in place using a blind stitch.

Using a double fold bias binder can be a great way to add a professional touch to your sewing projects. Once you’ve adjusted the binding to cover the stitch line, it’s important to press and pin it in place. To secure the binding, edgestitch close to the fold with the right side facing up. Finally, give the neckline a thorough press from both the right and wrong side of the top to ensure a crisp finish.

How Do You Use a Double Fold Bias Binder?

When it comes to using a double fold bias binder, there are a few steps to follow to achieve the desired outcome. To begin, adjust the binding so that the fold just covers the stitch line underneath. This ensures that the binding will neatly encase the raw edges of the fabric.

After adjusting the binding, press it to create crisp folds and pin it in place along the edge of the fabric. This will help to hold the binding securely as you work. It’s important to take your time at this stage to ensure that the binding is placed evenly and neatly.

Once the binding is pinned in place, it’s time to secure it permanently. Carefully edgestitch close to the fold of the bias binding, making sure to stitch through all layers of fabric. This not only provides a clean and finished look, but also reinforces the binding to ensure it stays in place over time.

After edgestitching the bias binding, it’s important to give the neckline (or any other area where the binding was applied) a good press. This will help to set the stitches and ensure that the binding lies flat and smooth. Be sure to press from both the right and wrong sides of the fabric to achieve the best results.
