What is an Iris Stitch Granny Square

The Iris stitch granny square uses repeating clusters to create an airy decorative texture that grows outward in rounds. The corners are formed using chain spaces and grouped stitches to keep the square flat and even as it increases. Although the stitch looks intricate, the repeating rounds quickly become easy to memorize. Iris stitch granny squares are ideal for blankets, cushion covers, bags, and decorative crochet projects because they create an airy, lightweight fabric with an elegant design.

The repeating Iris stitch clusters create a decorative lacy square with soft floral texture and excellent drape. Having stitch markers is useful when making one of these, as the corners can be difficult to see in the first couple of rounds. It is easy to mix up the corners with the chain 1 between your double crochet.

How to Crochet an Iris Granny Square

Note: I have referred to the iris stitch cluster which is (2 dc, ch1, 2 dc), simply for ease of explanation.

Round 1

• Start with a magic ring or ch4, and join with a sl st to make a ring.
• Into the ring (sc, ch2) 4 times.
• Sl st into first sc.

Round 2

• Sl st to ch2 sp.
• Ch3 (acts as first dc), 1 dc into ch2 sp. Ch1, 2 dc into same space.
• *Ch2, sk next sc.
• Mark your ch2 with a stitch marker; this is a corner.
• Work 2 dc, ch1, and 2 dc into same ch 1 sp. (Second corner.)
• Repeat from * twice more. Ch 2, place stitch marker.
• Close the round by working a sl st into the top of the first ch 3.

Round 3

• Sl st into cluster, to reach the ch2 sp. Sl st into ch2 space.
• Ch3 (1 dc),, work another dc into the same sp.
• Ch3, 2 dc. Mark the corner.
• * Skip next 2 dc, work iris-st into ch1 space.
• In the next ch2 space, work 2 dc, ch3, 2 dc. (mark corner) Repeat from *around.
• Close the round with a sl st into top of ch3.

Round 4

• Sl st into first dc, then into ch3 space.
• Ch3 (dc), work another dc into space.
• (Ch1, 2 dc, ch2, 2 dc, ch1, 2 dc) all into same ch3 space. (mark corner) you are working two iris stitches into the corner.
• Skip 4 dc, then work a iris st into next ch 1 sp.
• Work into next corner making a iris stitch twice, with 2 ch in between them, all into the same ch3 space.
• Repeat around and sl st into ch3.

Round 5 (start of repeat)

• Sl st into the first 4 sts, sl st into corner.
• Work corner: (ch3, 1 dc, ch3, 2 dc) into ch 2 space.
• * Work 1 iris-st into each space between iris along the side.
• Work corner again, by crocheting 2 dc, ch3, 2 dc. 
• Repeat from * all around. Sl st into ch 3.

Round 6

• Sl st into dc sts and into ch 3 space.
• Ch3, 1 dc, ch1, 2 dc, ch2, 2 dc, ch1, 2 dc all into the same space. (2 iris stitches into corner.)
• *Work 1 iris st into each large sp until you reach the corner.
• Work 2 iris-sts into the corner.
• Repeat from * around and close with a sl st.

Note: Every second round you are working much more stitches into each corner. If you did this every row, your square would not lie flat.

By now, your square may be the right size for you, or you may wish to continue making a bigger one. Repeat rounds 5 and 6 until your square is the desired size.

Understanding the Corners

The corners of the Iris stitch granny square are formed using chain spaces and grouped clusters. These corner increases allow the square to grow evenly while staying flat instead of curling.

Iris Stitch Granny Square – In Conclusion
