The Pattern!
Granny Square Calculation
- Crochet a sample square and measure it.
- Calculate needed squares for each section:
- Back panel: (Width in inches / square width) x (Length in inches / square length)
- Front panels: (Width / sq width) x (Length / sq length)
- Sleeves: (Length from armpit / sq width)
- Pockets: Add 2 squares
Example: For 4.7” squares and a back width of 23.5”, you need 5 squares. Adjust as needed for your size.
Odd/Even Square Widths
- If the width is odd: Leave a square gap for the neck opening.
- If the width is even: Make the top edge(s) of the uppermost front squares smaller by working 2 dc in each chain-1 space (instead of 3) and omitting chains between. Corners: 2 dc, ch-2, 3 dc.
This adjustment creates the neck gap needed for a comfortable fit.
Granny Square Construction
- Work as your chosen granny pattern instructs.
- For smaller upper edge on even panels, see above adjustment.
- Make all squares, then block gently.
Block using pins and a damp towel; specialty boards or chopsticks work well.
Panel Joining – Vertical (Columns)
- Lay out squares as planned; arrange with motifs facing the same direction.
- Use slip stitch join in back loops only. Fold squares with good sides together, join corner spaces, then slip stitch across each pair of back loop stitches.
- Fasten off and weave tails.
Repeat for all vertical (column) joins indicated (red lines in demonstration).
Panel Joining – Horizontal (Rows)
- Rotate panels and join with slip stitch join as above, matching stitches carefully.
- For pocket panels, layer pocket square atop panel, join along edge through all layers.
Cardigan Panel Assembly
- After joining all panels (back, fronts, sleeves), seam together at shoulders and sleeves using slip stitch join (green lines in demonstration).
- Folding: Fold along shoulder seams, then fold over sleeves.
- Seam along sides and length of sleeves.
Pocket Attachment
- On front panels, attach pocket squares during vertical join and seam bottom/side during ribbing and button band construction.
- Leave top edge of pocket unattached for opening.
Ribbing (Sleeve Cuffs, Hem, Button Band)
Sleeve Ribbing
- Scrunch up sleeve edge with sc decreases: Insert in corner space, pull up loop, insert in next, pull up loop, yarn over, pull through all.
- Repeat decrease around sleeve.
- Slip stitch to join.
- Chain to desired rib width (e.g., 13 for 3” rib), sc in second ch and across (12 sc).
- Slip stitch into next two stitches, turn, sc BLO across rib stitches.
- Repeat around, then seam ends of ribbing with slip stitch join on inside of sleeve.
Hem Ribbing
- With smaller hook, sc across bottom edge (working through both pocket and front panel layers where pockets are).
- Chain to desired rib width (e.g., 8 for 1.5”), sc in second ch and across (7 sc).
- Repeat slip stitch/sc BLO pattern as for sleeves.
Button Band
- With same size hook as body, sc up front opening (through ribbing and sides of squares, joining pocket sides).
- When reaching the neck, sc in each corner.
- Work 3 rows sc, then row for buttons:
- sc in first 4 sts, ch-2 (skipping next 2 sts), sc in next, repeat for all buttons.
- On next row, sc in each stitch and work 2 sc in each buttonhole.
- Work 6 rows in total.
Assembly & Finishing
- Weave in all tails securely.
- Block finished cardigan for the neatest fit.
- Sew buttons in line with buttonholes.
- Add pocket lining if desired or reinforce with extra stitches.
- Wash gently and dry flat.
Solution of problem
- If squares do not match up perfectly, block individually to correct sizing.
- If neck opening is too small, adjust the top edges of squares as detailed under "Odd/Even Square Widths".
- If rib is too tight or too loose, adjust length or stitch count for fit.

- Granny square jackets, vests, shrugs
- Cardigans for all sizes and ages
- Blankets, scarves, or bags with matching squares
