Here’s a clear, beginner-friendly, detailed guide for making super easy knitted slippers from a simple square using only basic knitting needles. These are sometimes called “grandma slippers” because they’re so quick and clever!

🧶 How to Make Very Easy Knitted Slippers From a Square

(Beginner Friendly – Uses Only Knit Stitch!)

These slippers are created by knitting one square, folding it in a special way, and sewing just a few seams. No shaping, no advanced stitches!

✔️ Materials You Need

• Yarn: Medium weight (worsted) or chunky yarn

• Knitting needles: Size recommended for your yarn (usually 4.5 mm–6 mm for worsted)

• Yarn needle for sewing seams

• Scissors

📏 Step 1 — Decide Your Size

Your slipper is made from a square. The length of one side of the square equals the length of your foot.

Square size guide

You can measure your foot and use that exact number.

🧵 Step 2 — Knit the Square

Cast on

Cast on enough stitches to make your knitting around as wide as your foot length.

Example:
If your foot is 24 cm, cast on enough stitches so the width is 24 cm.

Most people need 30–40 stitches with worsted yarn.

Knit the square

• Knit every row (garter stitch)

• Keep knitting until your work is as long as it is wide (forming a square)

💡 Tip: Fold your work diagonally into a triangle. If the edges match, it’s a perfect square!

Bind off

Bind off loosely so the edge doesn’t tighten.

🪡 Step 3 — Folding the Square Into a Slipper

This is the fun part!

Place your knitted square flat in front of you like a diamond shape:

Step 3A — Fold the left and right corners in

Bring the left corner and right corner toward each other so they overlap in the middle.

Step 3B — Toes

Sew from the top corner down to the center where the two side points meet.
This closes the toe of the slipper.

Step 3C — Heel

Now locate the bottom corner of the square.
This becomes the heel.

Fold it up and sew about 1/3 to halfway up to form the heel cup.

🩴 Step 4 — Try On and Adjust

Slip it onto your foot:

• If the slipper feels loose → sew the heel seam a little higher

• If it feels tight → loosen the toe seam slightly

You can add:

• A pom-pom

• A button

• Ribbing around the ankle

• A decorative seam on top
