Understanding Your Patterns: Assembly and Marking of the Square Neck Crop Top Pattern

To make your fabulous broad neck crop top, getting accustomed with your pattern is key! Start by laying your fabric on a flat surface, checking for any directional patterns. Flip through your pattern instructions and stick to the layout guide like your sewing BFF.
Once your fabric is prepped and ready, it’s time to dive into the pattern-marking phase! Place those pattern pieces, line up the arrows with your fabric’s vibes, and secure with weights or pins – no slipping allowed! Remember, mark it up on the wrong side to keep the finished look flawless.
Now, let’s talk details! Notches, darts, and grainlines – these little guys are the superheroes of precise assembly. Grab your favorite marking tool like a chalk and give them a new home on the wrong side of your fabric.
For the broad neck crop top, focus on the following pattern pieces:

A. Front Bodice

Cut one fabric piece. Ensure you transfer all necessary markings accurately, especially those indicating the placement of darts, notches, and the center front.

B. Back Bodice

Cut one fabric piece. Transfer markings similar to the front bodice, emphasizing the center back, notches, and any darts.

C. Sleeve

Cut two fabric pieces. Mark key points like the top of the sleeve, notches, and the placement of any gathers or pleats.

To minimize fabric wastage, consult the cutting layout provided in the next section before cutting.
If printing at home, utilize the A4 Pattern, and for print at a copy shop, opt for the A0 Pattern for convenience.

Steps To Follow For Sewing a Square Neck Crop Top

Follow these steps to sew a well-fitted and professionally finished broad neck crop top:

Step 1: Cutting Layout

To sew a broad neck crop top, begin by carefully arranging pattern pieces on the fabric according to the cutting layout diagram shown below, ensuring the grainline aligns with the selvage.

Pin the pieces to secure them before using fabric shears to cut along traced lines, removing any notches and markings for accurate assembly. Transfer additional markings like circles and fold lines to the wrong side of the fabric. Mark the center front of pieces cut on the fold to aid alignment. Consider purchasing extra fabric length for prints or nap.

Step 2: Prepare Dart Openings

Fold the ends of the dart opening, bringing them together with the right sides facing each other, forming a triangle shape.
Sew along the marked line, securing the dart opening.

Step 3: Sew Sleeve Darts

Sew both the darts on the sleeves.

Step 4: Attach Front Sleeve

Match the front armhole notches on the sleeve to the corresponding notches on the front body fabric.
Pin the fabrics together and sew along the armhole to attach the front sleeve.

Step 5: Attach Back Sleeves

Similarly, match the back armhole notches and attach the back sleeves to the back body fabric.
Sew along the armhole.

Step 6: Binding the Neckline

Place the binding strip inside the binder, stitching about 1 inch (See picture 5a).
Insert the neck seam allowance inside the bind and start sewing the neckline from one open end to the other (See picture 5b).
Cut any excess strip after securing the binding in place. The stitching of the bind strip can be seen in picture 5c.

Step 7: Attach Second Sleeve

Repeat the process to attach the other sleeve to the front body, ensuring that this step also closes the binding ends.

Step 8: Sew Side Seams

Sew the side seams facing right-on-right, starting from the sleeves and progressing towards the hem.

Step 9: Hemming

Fold the hem on the wrong side by 0.7 inches (or your preferred measurement).
Use an iron to flatten the fold and secure it in position with pins.
Sew a straight stitch along the top edge of the fold, starting from one side seam and continuing around the entire hem.
