Fabric Recommendation

For crafting a long sleeve crop top, opt for light to medium weight knit fabrics like cotton blends, jersey, lycra, stretch velour, or stretch velvet.
These are renowned for their breathable comfort, elasticity and flexibility, plush softness with stretch, and luxurious texture.

The poly-nylon elastane fabric is celebrated for its smooth, soft, and lightweight feel. This fabric resists bagging and sagging, is scratch-resistant, and outshines rubber in strength and durability—all while maintaining a feather-light weight.

Steps To Follow For Sewing a Long Sleeve Crop Top

Embark on a stylish sewing adventure as I guide you through the steps to create your own long sleeve crop top:

Allow me to simplify things for you! Opt for the overlock stitch in most sewing situations, although the zigzag stitch is also a good choice. If you want a tidy hem, choose the flatlock stitch. If your sewing machine permits, reduce the pressure on the presser foot, especially when dealing with stretchy fabric. And here’s a clever tip: practice your stitching before tackling the actual project.

Step 1: Cutting Layout

Ensure your garment is cut on-grain by following the provided pattern layout. While the layout is non-directional, extra fabric length is necessary for materials with nap or prints.

Step 2: Lay Out Your Pattern Pieces

Arrange your pattern pieces according to the cutting layout diagrams. Start by placing pieces meant for the fold and ensure the grainline arrow runs parallel to the selvage.

Step 3: Cut Your Fabric

If you’re using a rotary cutter, cut out the pattern pieces directly. If using fabric shears, trace the pattern pieces and then cut them out, ensuring you remove any pen, pencil, or chalk lines. Don’t forget to cut out any notches for proper alignment during assembly.

Step 4: Transfer Pattern Markings

Use a marking pen, pencil, or chalk to transfer essential markings (circles, buttonholes, fold lines) to the wrong side of the fabric. Mark the center front of pieces cut on the fold to aid in accurate alignment.

Step 5: Cutting Bias Strip

Begin by cutting a bias strip, approximately 1 1⁄2 inches wide, at a 45° degree angle from the selvage. Ensure to add an extra 3 inches to the neckline for both shaping and securing the binding.

Step 6: Attaching Bias Strip to Back Neckline

Position the bias strip on the back neckline with right sides facing each other. Seam them together along the seamline.

Understitch the seam allowance, combining the bias strip and seam allowances along the edge (See Picture 2a).

Create a rectangular box by folding the edge inward and sew along the edge to securely bind everything together.

Step 7: Applying Interfacing to Front Neckline

Place interfacing fabric on the front neckline, ensuring it faces right-on-right.

Use an overlock stitch to serge the interfacing edge (See Picture 3a).

Sew them together (See Picture 3b), then turn the interfacing to the backside and understitch for a polished finish (See Picture 3c and Picture 3d).

Step 8: Shoulder Seams

Bring the front and back bodices together with right sides facing.

Pin them for stability and proceed to sew both shoulder seams.

Step 9: Attaching Sleeves

Align the sleeve and bodice armhole seam, ensuring a right-on-right orientation.

Accurately match the mid-notch and shoulder lines before pinning them together.

Sew the pieces, repeating the process for the other sleeve (See Picture 5c).

Step 10: Side Seams

Connect the front and back bodices with right sides facing. Sew the side seams from the sleeve end to the hemline.

Step 11: Hemming

For the hemline and both sleeves, fold them inside out (facing wrong-on-wrong). Commence sewing from one seam line intersection and return to it. Opt for a flatlock stitch for a clean and polished finish.

Tip: To enhance your sewing experience, it is recommended to iron the pattern pieces after completing each step.
