What is a slot seam?

A slot seam is used to sew a piece of fabric to a garment or textile by inserting a ‘slot’ between two parts of the fabric. It is made by converting a flat piece of fabric (generally a different color) between the two folded edges of the main fabric pieces, and then the fabric pieces are sewn in parallel to make a tunnel or ‘slot.’ This procedure adorns a piece of clothing or textile and ensures its structural integrity.

Why Use a Slot Seam?

Many people choose slot seams for their two-fold benefits: they can act as ornaments and structural reinforcements. Slot seams are a great way to apply the contrast of different fabrics, colors, or patterns to clothes and interiors, making them a hot trend with designers for quite some time.

How Do I Sew a Slot Seam?

Get Your Trim Ready

Cut the main fabric and an even strip, either the same or different from the main fabric to the slot.

Put a Fold and Iron

Scarce fabric pieces, on which we will make a slot seam with our folds and then iron them for sharp edges.

Apply Strip

Form one strip of material between the layers on one side of the main fabric and line up the fold on the other.

Sew the Slot

Close to the fold line enclosing the notch, and stitch the strip at the end. Do the same on the opposite side. In conclusion, steam the dull gorge to engrave the pattern firmly.

When Should I Opt for a Slot Seam?

First, slot seams can be used for decorative purposes whenever a garment needs subtle yet catchy detailing. They are also required in specific places that need extra reinforcement but avoid the bulkiness of regular seams. Finally, slot seams are great for designs that can profit from contrasting fabric strips.

What are the common issues with slot seams, and how can they be avoided?

Here are some:

Misalignment

Be sure to work with the correctly cut and aligned pieces. Pinning or basting helps maintain alignment.

Fraying

Go for the rust-resistant fabrics or use edge finishes for the slot ends.

Undefined Slots

Many times, you have to learn how to press correctly. Creating the correct slots and folds before pressing can reveal the clarity of the sewed place.

How to Fix Mistakes in Slot Seams?

Here’s how you can fix mistakes in slot seams:

Unpicking

Use a seam ripper to work painstakingly on the stitches, but do not ruin the fabric.

Realign

Besides the alignment problem, adjust the pieces correctly and pin or bast beforehand. Then sew again.

Strengthen

Examine the edges; if they are scuffed, clip the fringes away before you seal them or apply a no-fray wrap.
