Crochet Granny Triangle Bandana Pattern

Foundation: Make a slipknot, ch6

Row 1: In 6th ch from hook, [dc3, ch2, dc3, ch1, dc] (1 cluster on each side)

If it’s hard to fit all these stitches in that one chain, undo your 6 chains and make the first one looser.

The bolded stitches denote the middle corner of the triangle

Row 2: ch5, turn, dc3 in ch1-sp, ch1, [dc3, ch2, dc3] in ch2-sp, ch1, [dc3, ch1, dc] in last sp (2 clusters on each side)

The chain 5 replaces a double crochet and chain 1, which is mirrored for the end of each row.

Row 3: ch5, turn, [dc3 in next ch1-sp, ch1] 2 times, [dc3, ch2, dc3] in ch2-sp, ch1, dc3 in next ch1-sp, ch1, [dc3, ch1, dc] in last sp (3 clusters on each side)

Row 4: ch5, turn, [dc3 in next ch1-sp, ch1] 3 times, [dc3, ch2, dc3] in ch2-sp, [ch1, dc3 in next ch1-sp] 2 times, ch1, [dc3, ch1, dc] in last sp (4 clusters on each side)

Row 5: ch5, turn, [dc3 in next ch1-sp, ch1] 4 times, [dc3, ch2, dc3] in ch2-sp, [ch1, dc3 in next ch1-sp] 3 times, ch1, [dc3, ch1, dc] in last sp (5 clusters on each side)

Rows 6-18: Repeat the row before with an extra [dc3 in next ch1-sp, ch1] before the middle corner and an extra [ch1, dc3 in next ch1-sp] after the middle corner

Note: Continue adding rows until the triangle is big enough to cover your head. Do fewer rows for a smaller bandana or more rows for a bigger bandana.

For example:

Row 6: ch5, turn, [dc3 in next ch1-sp, ch1] 5 times, [dc3, ch2, dc3] in ch2-sp, [ch1, dc3 in next ch1-sp] 4 times, ch1, [dc3, ch1, dc] in last sp (6 clusters on each side)

Row 7: ch5, turn, [dc3 in next ch1-sp, ch1] 6 times, [dc3, ch2, dc3] in ch2-sp, [ch1, dc3 in next ch1-sp] 5 times, ch1, [dc3, ch1, dc] in last sp (7 clusters on each side)

…

Row 17: ch5, turn, [dc3 in next ch1-sp, ch1] 16 times, [dc3, ch2, dc3] in ch2-sp, [ch1, dc3 in next ch1-sp] 15 times, ch1, [dc3, ch1, dc] in last sp (17 clusters on each side)

Row 18: ch5, turn, [dc3 in next ch1-sp, ch1] 17 times, [dc3, ch2, dc3] in ch2-sp, [ch1, dc3 in next ch1-sp] 16 times, ch1, [dc3, ch1, dc] in last sp (18 clusters on each side)
