How to Make (and Discover!) the Easiest Crochet Sweater in the World – In All Sizes

❤️ Why This Sweater is So Easy:

  • Uses only rectangles (no shaping or complicated increases/decreases).

  • Can be customized for any size – from baby to plus size adults.

  • Uses basic stitches: mostly double crochet or half double crochet.

  • Minimal sewing (just two seams + sleeves if desired).

  • Works up quickly with medium to bulky yarn.


Materials You’ll Need:

Item Details
Yarn Worsted (#4) or Bulky (#5) – Acrylic or Wool blend
Hook 6.0 mm (J) or 6.5 mm (K) – depending on your yarn
Measuring tape To get accurate body measurements
Scissors For cutting yarn
Tapestry needle For sewing pieces together
Stitch markers Optional, but helpful for beginners

Step 1: Take Your Measurements

To make the sweater fit any size, you’ll need 3 basic measurements:

  1. Bust/Chest Width – Around the fullest part of your chest.

  2. Sweater Length – From your shoulder down to where you want the hem to fall.

  3. Sleeve Length (optional) – From the shoulder to wrist (if making long sleeves).


Step 2: Basic Pattern Structure

The sweater is made of 4 rectangles:

  • 2 Body Panels (Front and Back): Width = half of bust + ease (around 2-4 inches extra). Length = desired sweater length.

  • 2 Sleeves (optional): Width = upper arm circumference + ease; Length = from shoulder to wrist.

For a cardigan version: Just make one of the front panels half as wide as the back panel and make two of them.


Step 3: Crochet the Rectangles

Use half double crochet (hdc) or double crochet (dc) stitch across.

Basic Panel Instructions (example in HDC):

Row 1: Ch to the desired width (based on your measurements).
Row 2: Hdc in 2nd ch from hook and across. Ch 1, turn.
Repeat: Until piece is the desired length.
Fasten off.

Repeat for the second body panel.

For sleeves: Follow same steps, but use sleeve measurements.

✅ Tip: Keep your stitch count consistent. Use stitch markers every 10 stitches to help.


Step 4: Assembling the Sweater

Lay both body panels flat, one on top of the other.

To Assemble:

  1. Shoulder Seams: Sew the top 5–7 inches on each side, leaving a neck hole in the center.

  2. Side Seams: Sew from the bottom up, stopping 7–9 inches from the top to leave armholes.

  3. Attach Sleeves (Optional): Fold each sleeve rectangle in half lengthwise, sew side closed. Attach to armholes with whipstitch or mattress stitch.

You can also leave it sleeveless and call it a vest!


✨ Optional: Add Ribbing or Borders

To make your sweater look more polished:

  • Add ribbing to the hem, cuffs, and neckline using front post/back post double crochet (FPDC/BPDC) or a simple slip stitch ribbing.

  • Add buttons if you’re making a cardigan.

  • Add a hood or pockets if you’re feeling adventurous.
