Here is a clear, step-by-step, detailed guide on how to knit slippers from a simple square — one of the easiest beginner knitting projects!

🧶 How to Knit Slippers Out of a Square (Easy & Simple!)

This method creates cozy slippers using only one knitted square per slipper. Perfect for beginners, fast, and customizable!

✅ Materials You Will Need

Yarn: Medium (worsted) or bulky weight yarn
Knitting needles: Size that matches your yarn (usually 5–6 mm for bulky, 4–5 mm for worsted)
Yarn needle/darning needle for sewing
Scissors
Measuring tape

🧵 Step 1: Knit Your Square

Size of the Square

Measure the length of your foot from heel to toe.
Your knitted square should be:

👉 Length = Foot length
👉 Width = Same as length (since it’s a square)

Example:
If your foot is 9 inches (23 cm):
→ Knit a 9 × 9 inch square.

How to Knit the Square

Use the garter stitch (knit every row) — stretchy and perfect for slippers.

Cast on enough stitches to reach your desired width.
Knit every row until the piece becomes a perfect square.
Cast off loosely.

🧵 Step 2: Fold the Square

Lay the square flat like a diamond shape (looks like a kite):

🧵 Step 3: Sew the Toe

Bring the left and right corners together at the front.
Stitch them together about one-third to halfway up — this forms the toe of the slipper.

It will begin to cup like the front of a shoe.

🧵 Step 4: Create the Heel

Now go to the bottom point of the square.

Fold the bottom corner up toward the center back of the slipper.
Sew the sides of this bottom section together up toward the ankle area.
Leave the top open — that’s where your foot goes in.

🧵 Step 5: Try Them On & Adjust

Slip your foot inside:

If they’re too loose: sew a bit more at the toe or heel.
If they’re snug: you can gently stretch garter stitch.
Optional: Add pom-poms, buttons, or a cuff.

🧵 Optional: Add a Ribbed Cuff

Pick up stitches around the ankle opening and knit a 1×1 rib (K1, P1) for 5–10 rows.
This makes the slippers look more finished and helps them grip the foot.

🧵 Sizing Guide (Quick Reference)

For approximate square sizes:

Foot Size	Square Size
Kids (5–8 yrs)	6–7 in (15–18 cm)
Women’s Small	8 in (20 cm)
Women’s Medium / Men’s Small	9 in (23 cm)
Women’s Large / Men’s Medium	10 in (25 cm)
Men’s Large	11 in (28 cm)

🧶 Tips for Success

Garter stitch works best because it’s stretchy.
Use soft, warm yarn like acrylic or wool.
Thicker yarn = faster project!
You can use two strands of yarn together to make slippers sturdier.

🩴 How It Works (Simple Explanation)

The square folds around your foot like an envelope:

Two corners make the toe
One corner folds up to make the heel
The top stays open for the foot

This is why it’s such a great beginner project.
