Gusset Sewing: How to Sew a Gusset to Garments

 

Things you will need for gusset sewing:

• A piece of fabric
• Sewing needle and thread
• Tape measure
• Pair of Scissors
• Sewing machine

Step 1: Remove the Stitching

When your garments are too tight, you can simply add a gusset for extra space. Gussets are the little triangular pattern piece added to a garment. The main purpose of a gusset is to expand some parts of your pants, dress, shirts, and other clothing items–giving the wearer more room to move.

For this gusset tutorial, we will try adding a gusset to a blouse or a garment. Remove the stitching on the area where you want to add the gusset. Turn the sleeve to the wrong side and backstitch the ends of the ripped seam so the sleeve doesn’t come undone.

Tips: 

• The fabric used for gusset should be exactly the same as the clothing.
• Pay attention to how much fabric you need for your gusset.
• Gusset should be added subtly on the clothing. Make sure it doesn’t bulge out.

Step 2: Clip the Seam

Clip right up to the seam where you stopped the backstitch (make sure to avoid cutting out the thread). By doing that, you release the seam allowance so you can start working on that area to add your gusset.

Step 3: Measure the Upper Width and Length

Pull the garment apart and measure the space you need for the gusset. Then, measure the length from the top of the garment down to where you clipped or stop.

Tips:

• Notice the shape of the fabric because that will be the shape of your gusset.
• Always add half an inch wider and longer for the seam allowance.

Step 4: Draw and Cut the Gusset on the Fabric

Take the fabric for your gusset and draw the shape using your measurements. It is easier to draw a center line of the gusset, fold it in half, and mark the fabric according to the sizes. Don’t forget your 5/8″ seam allowance, before cutting the fabric. Also, draw a line or marks for easy cutting.

Step 5: Pin the Gusset in Place

Turn the garment piece over and pin the gusset in place facing right sides together.

Tip: Pin the triangular fabric to the area you want to add a gusset into. The triangular fabric with longer sides should be pinned to the sides of the clothing, while the narrow side would be attached at the top or bottom area.

Step 6: Sew the Gusset

When you start sewing, put the needle down at the tip where you reinforce the bottom of the seam. Sew the gusset beginning from the bottom right straight up the end. Do the same on all sides of the gusset.

Tip: Make sure the edges line up well to make it unnoticeable and look more polished. When the edges don’t line up, you need to remove the stitches and do it again.
