Adding Side Slits to a Sweatshirt: A Stylish and Functional Modification

Side slits are a trendy and practical addition to a sweatshirt, allowing for better mobility and a unique fashion statement. Whether you want to revamp an old sweatshirt or customize a new one, adding side slits can be a relatively simple DIY project. In this article, we will guide you through the process of adding side slits to a sweatshirt, step-by-step.

Materials Needed

Before you get started, gather the following materials:

  • A sweatshirt
  • Fabric scissors
  • Pins
  • Measuring tape or ruler
  • Sewing machine or needle and thread
  • Optional: Seam ripper

Step 1: Choose the Placement and Length of the Side Slits

The first step in adding side slits to a sweatshirt is deciding where you want the slits to be and how long you want them to be. You can choose to have slits starting at the waist or slightly higher up, depending on your preference. Additionally, consider the length of the slits. Longer slits can provide a more dramatic effect, while shorter slits offer a subtle touch.

To determine the desired slit length, try on the sweatshirt and use a measuring tape or ruler to mark the length on each side. Remember to account for any existing hem if you want the slits to start below it. Use pins to secure the marked spots.

If the sweatshirt has side seams, consider whether you want the slits to align with the seams or be offset. Aligning the slits with the side seams can create a cleaner and more symmetrical look.

Step 2: Prepare the Sweatshirt

Once you have determined the placement and length of the side slits, it's time to prepare the sweatshirt for the modification.

If your sweatshirt has a bottom hem, use a seam ripper to carefully remove the stitches in the area where the slits will be. This will create a neater finish for the slits and prevent any unnecessary bulk.

If your sweatshirt does not have a bottom hem or if you prefer to keep it intact, skip this step. You can still proceed with adding the side slits directly on the garment.

Step 3: Cut the Side Slits

With the sweatshirt prepared, it's time to cut the side slits.

Starting from the marked spots, use fabric scissors to carefully cut straight lines on both sides of the sweatshirt. The width of the slits is up to you, but a common width is around 2 to 4 inches. Remember to cut through both the front and back layers of the sweatshirt.

It's important to cut only where you marked and to avoid cutting too far up or down. Take your time and make precise cuts to ensure the slits are symmetrical.

Step 4: Finish the Slits

To prevent fraying and create a clean finish, you have a few options for finishing the side slits.

If you have a sewing machine, you can use a zigzag stitch or an overlock stitch along the raw edges of the slits. This will secure the fabric and prevent it from unraveling. Alternatively, you can use a serger if you have access to one.

If you don't have a sewing machine, you can finish the slits by hand using a needle and thread. Use a whipstitch or a blanket stitch along the edges to secure the fabric and prevent fraying.

Creating a Unique Look with Side Slits: Different Styles and Design Ideas

Side slits offer endless possibilities for customization and style. Here are some design ideas to inspire you:

Asymmetric Slits

Instead of cutting the slits directly across, consider an asymmetric style. Create slits that are longer on one side and shorter on the other, or slits at different heights. This adds an element of uniqueness and creates an eye-catching detail.

For the asymmetric look, mark and cut the desired slit lengths accordingly. Remember to maintain symmetry on each side, even though the lengths differ.

After cutting the slits, follow the same steps for finishing the raw edges as described earlier.

Lace-Up Slits

Lace-up slits can add a touch of edginess and style to your sweatshirt. Instead of leaving the slits open, thread a string or ribbon through them to create a lace-up effect.

Start by marking and cutting the slits as usual. Then, use a small handheld hole punch or a fabric punch tool to create evenly spaced holes along the slit edges. Lace the string or ribbon through the holes, crisscrossing it for a decorative look. Tie the ends of the string or ribbon securely to keep the lacing in place.

This style works particularly well with thicker sweatshirt fabrics, as they provide more strength and structure for the laces.

Layered Slits

Layered slits can add dimension and visual interest to your sweatshirt. Instead of cutting a single slit on each side, create multiple slits or stack slits on top of each other.

To achieve the layered look, mark and cut the main slit as desired. Then, create additional shorter slits above or below the main slit. These shorter slits can be of different lengths or the same length for a uniform layered effect.

As with other slit styles, finish the raw edges of each slit to ensure a clean and polished appearance.
