Sometimes, this kind of hot pad is also called diagonal potholder or origami potholder because the magic construction is all about the way you fold it.

Diagonal Potholders

Whether you call it a magic square, a diagonally crocheted potholder, or an origami hot pad, the idea behind its construction is simple and brilliant at the same time!

The first step is to make a simple foundation chain and crochet all around it. Then, you keep crocheting in the round to form a sort of bag or pocket, which you can fold on its own to form a square.

Because of the it’s constructed, the magic square potholder is double-thick and it’s really a great ally in the kitchen when it comes to handle hot pots and pans!

  • 5.0-mm (H/8 USA, 6 UK) Crochet Hook
  • Aran (4, Medium) Cotton Yarn
  • Tapestry Needle


I used 1 skein of Drops Loves You 8/8 (93 yds, 85 m per 50 g).

Best Yarn for Crochet Potholders

In general, it is always best to crochet potholders, hot pads, and trivets using cotton yarn, which doesn’t melt in contact with hot stuff.

For my potholder, I used Drops Loves You 8/8, but there are plenty of comparable yarns on the market. Here are a few examples:


  • BLO – Back Loop Only
  • Ch – Chain
  • RS – Right Side
  • Sc – Single Crochet
  • Sl St – Slip Stitch
  • St – Stitch


Back Loop Only (BLO)

7” (18 cm)


18 BLO sc for 15 rows in 4” (10 cm)

For the magic square potholder, it is not crucial to meet the exact gauge.

Crochet a Potholder in any size

You can crochet the magic square hot pad using any yarn with the appropriate hook following one simple rule.

Your initial chain is going to be the diagonal of your potholder.

So, since it is a square, you can easily calculate the final size of your potholder based on the length of your initial chain, or just refer to the measurements in the image below.

Fold your Potholder

Hold your work up with one hand at the start of round 1 and the other hand at the end of round 1.

Slide your hands up to the last round and push the sides toward the center (photo 6: halfway through the project; photo 7: what your work should look like when all 19 rounds are complete).

The important thing is that the folded sides of the potholder touch in the middle!

Depending on your tension, you might need to crochet an additional round or frog (undo) one if the sides overlap.

Fasten off leaving a long tail for sewing. Your tail should be approximately twice the diagonal of your potholder.


Match the stitches on the two sides of the potholder and seam them together using the long yarn tail. For seaming, use the mattress stitch, the whip stitch, or your favorite sewing method.
