Cozy Knitted Slippers

Simple boot-style slippers knitted flat on straight needles, then folded and seamed. Beginner-friendly: only knits, basic decreases, and mattress stitch. No double-pointed needles, no picking up stitches, and no short rows.

Skill Level

Beginner

Sizes

Small (Medium, Large) To fit women’s US shoe sizes 5–6 (7–8, 9–10) / EU 36–37 (38–39, 40–42). Large also fits men’s US 8–9. Choose size by foot length.

Finished Measurements

• Sole length: 9 (10, 11)" / 23 (25.5, 28) cm
• Circumference (fabric width, unstretched): 8 (8¾, 9¾)" / 20.5 (22, 25) cm Slippers have negative-to-zero ease and stretch to fit; garter stitch hugs the foot.

Yarn

Worsted weight yarn (CYC 4); wool or wool-blend recommended for warmth and natural grip.

• Approximately 160 (190, 220) yd / 145 (175, 200) m total for the pair Solid or lightly variegated colors work well. Pure acrylic is acceptable but can be slippery on hard floors—add non-slip treatment (see Finishing).

Example: Cascade 220, Cascade 220 Superwash, Lion Brand Wool-Ease, or similar (100 g / ~220 yd skeins); 1 skein is usually enough for Small or Medium, 1–2 for Large.

Needles

US 8 / 5 mm straight needles (or size needed to obtain gauge)

Notions

• Tapestry needle
• Scissors
• Optional: stitch markers, pom-pom maker, non-slip fabric paint or suede sole patches, contrasting yarn for embroidery

Gauge

18 sts and 36 rows = 4" / 10 cm in garter stitch (knit every row), blocked gently. Take time to check gauge. Row gauge directly controls sole length.

Abbreviations (US)

• BO: bind off
• CO: cast on
• k: knit
• k2tog: knit 2 stitches together (right-leaning decrease)
• RS: right side
• ssk: slip, slip, knit (left-leaning decrease)
• st(s): stitch(es)
• WS: wrong side

Notes

• Slippers are worked flat from heel to toe. The piece is folded in half lengthwise so the long selvedges meet on top of the foot. The center fold becomes the sole.
• Garter stitch looks the same on both sides; mark the RS with a removable marker or scrap yarn if desired.
• Instructions are for one slipper; make two alike.
• When only one number is given it applies to all sizes. Numbers in parentheses are for Medium and Large.
• Inline stitch counts are shown after shaping rows.

Pattern Instructions

Slipper (make 2)

With straight needles, CO 36 (40, 44) sts.

Heel and foot Work in garter stitch (knit every row) until piece measures 7 (8, 9)" / 18 (20.5, 23) cm from CO edge. (At 9 rows per inch this is approximately 63 (72, 81) rows; measure rather than relying solely on row count.)

Toe Shaping

Begin decreases. Maintain garter stitch throughout.

Dec row (RS): K1, k2tog, knit to last 3 sts, ssk, k1.
2 sts decreased.
Next row (WS): Knit.

Repeat the last 2 rows 9 (10, 11) more times.
16 (18, 20) sts remain.
(Validation: Small 36 − 2×10 = 16 ✓; Medium 40 − 2×11 = 18 ✓; Large 44 − 2×12 = 20 ✓.)

Next row (RS): Knit. BO all sts knitwise. Cut yarn, leaving a 18" / 45 cm tail for seaming.

Finishing

1. Fold: Fold each slipper in half lengthwise with WS together (RS out) so the two long selvedges meet. The CO edge is the heel; the BO edge is the toe tip. The fold is the center of the sole.

2. Heel seam: Using the long CO tail (or a new length of yarn) and mattress stitch, sew the CO edge closed from the fold up to the top edges. Work firmly but do not cinch.

3. Toe and top seam: Thread the BO tail. Beginning at the toe tip, mattress-stitch the two selvedges together along the top of the foot for approximately 3 (3¼, 3½)" / 7.5 (8.5, 9) cm, or until the remaining opening comfortably fits over the ankle. Weave in the end securely on the WS.

4. Weave in all remaining ends on the WS. Gently steam-block or wet-block if desired—pat into shape and do not stretch the sole length.

5. Optional non-slip sole: Apply fabric-paint dots or lines to the bottom, or sew on purchased suede/leather slipper patches for traction, especially if using acrylic yarn.

Customization Options

• Stitch pattern: Replace garter with seed stitch for extra texture and grip, or work a few rows of 1×1 rib at the top edges before seaming for a snugger ankle. Stockinette may curl—add garter borders if used.
• Stripes: Change colors every 4–6 rows; carry yarn loosely up the side or cut and weave ends.
• Cuff look: After seaming, fold the top opening down 1" for a faux cuff, or crochet a simple crab-stitch edging around the opening if desired.
• Double-thick sole: Hold two strands of worsted together for the center third of the stitches only (mark the sole section) for extra durability.
• Embellishments: Add a pom-pom to the toe, sew on buttons, or embroider initials/contrast motifs after seaming.
• Length tweak: For a half-size adjustment, work ½" more or less before starting toe decreases.

Care

Hand wash cool; lay flat to dry. Wool blends may be machine-washed gently if the ball band allows. Re-block lightly if needed.

Enjoy your cozy slippers!
