Special Stitches

Bubble Stitch on Raglan Line — Chain loops worked multiple times into the same stitch to create a raised bubble that serves as raglan seam and visual element.

The Crochet Pattern

Step 1: Planning and Making a Sample

Measure desired neckline circumference (~60 cm).
Make a sample swatch in the stitch pattern to determine stitches per cm.
Example: 88 stitches for neckline circumference of 60 cm. Always use an even number of stitches for raglan symmetry.
Save

Step 2: Chain and Join for Neckline

Chain the number of stitches calculated (example: 88).
Join gently with single crochet in the back loop of the first chain to form a ring, making sure chain is not twisted. This creates a smooth edge to work around.

Step 3: First Round — Half Double Crochets in Back Loops

Work half double crochets (hdc) in the back loop only of each stitch around.
Mark raglan points: subtract 4 stitches for raglan lines, split remaining stitches evenly between front/back panels and sleeves.
Attach stitch markers at raglan positions (4 markers evenly spaced).
Save

Step 4: Create the Bubble Raglan Lines

Locate raglan stitch. Work bubble by:
- Yarn over, insert hook into raglan stitch, yarn over, pull through. Repeat yarn over–pull through several times (6 loops is common) to create a “bubble” that stands out.
- Pull yarn through all loops except last one, finish with one last stitch.
Between bubbles, work the body and sleeves using wrapped half double crochets (hdc wrapped around 3 loops).

Step 5: Working Rows Back and Forth

After each round, turn work to begin next row going back in opposite direction.
Work bubble raglan line stitches consistently on raglan stitch rows to hide seams.
Count stitches carefully. The raglan bubbles serve as convenient markers for stitch counting.
Increase on both sides of raglan bubble—this shapes raglan sleeve smoothly and evenly.
Save

Step 6: Separating Sleeves

Once raglan yoke reaches desired length, separate sleeves by skipping sleeve stitches, joining front and back body panels across underarm gap.
For separation, slip stitch or join chains may be used to close gap neatly.
Mark the separation points clearly; these will form armholes.

Step 7: Working Body and Sleeves Separately

Body: Continue working half double crochet stitches back and forth in rows on body stitches.
Sleeves: Join yarn at sleeve stitches; continue working back and forth half double crochets (wrapped).
Adjust sleeve length as desired, working ribbing cuff if preferred.
Save

Step 8: Making the Sweater Cuffs and Bottom Ribbing

Work ribbing in single crochets with yarn over in back loop only to maintain elasticity.
Length of cuff or hem ribbing can be customized for fit and style.
Ribbing is worked continuously in the round or back and forth as you prefer, keeping stitches even.

Step 9: Finishing Neckline

For neckline finishing, work several rounds of front relief half double crochets (wound hdc) in spiral without joining.
Mark the first stitch to keep track of rounds.
Neckline ribbing rounds help shape collar and create a gentle curve.
End neckline by weaving in yarn tails invisibly.

Neckline — approx. 60 cm circumference, stretches comfortably
Sleeve length: approx. ¾ length or shorter as preferred
Body width (underarm): approx. 52 cm flat, roomy fit
