Understanding Crochet Terms for Your Triangle Pattern

Before beginning your triangle crochet , familiarize yourself with these abbreviations (US terms):

ch: Chain
sc: Single crochet
inc: Increase (work 2 single crochets in the same stitch)
Row: A single line of stitches from one side to the other

Triangle Crochet Instructions

This triangle crochet creates a symmetrical triangle with increases at both edges of alternating rows. The result is a triangle with a straight bottom edge and a point at the top.

Starting Your Triangle Crochet

Row 1: Chain 2, then turn your work.

Row 2: In the second chain from your hook, work an increase (2 sc in the same stitch). You now have 2 stitches. Chain 1 and turn. Note: Always skip the turning chains in this pattern.

Row 3: Work 1 sc in each of the 2 stitches (2 stitches total). Chain 1 and turn.

Building Your Triangle Crochet

Row 4: Work an increase in each stitch (inc x2), giving you 4 stitches total. Chain 1 and turn.

Row 5: Work 1 sc in each of the 4 stitches (4 stitches total). Chain 1 and turn.

Row 6: Inc, sc in the next 2 stitches, inc (6 stitches total). Chain 1 and turn.

Row 7: Work 1 sc in each of the 6 stitches (6 stitches total). Chain 1 and turn.

Row 8: Inc, sc in the next 4 stitches, inc (8 stitches total). Chain 1 and turn.

Row 9: Work 1 sc in each of the 8 stitches (8 stitches total). Chain 1 and turn.

Row 10: Inc, sc in the next 6 stitches, inc (10 stitches total). Chain 1 and turn.

Row 11: Work 1 sc in each of the 10 stitches (10 stitches total). Chain 1 and turn.

Continuing Your Triangle Crochet

Notice the pattern? On even-numbered rows, you increase at both ends of the row. On odd-numbered rows, you work one sc in each stitch across. Let’s continue:

Row 12: Inc, sc in the next 8 stitches, inc (12 stitches total). Chain 1 and turn.

Row 13: Work 1 sc in each of the 12 stitches. Chain 1 and turn.

Row 14: Inc, sc in the next 10 stitches, inc (14 stitches total). Chain 1 and turn.

Row 15: Work 1 sc in each of the 14 stitches. Chain 1 and turn.

Row 16: Inc, sc in the next 12 stitches, inc (16 stitches total). Chain 1 and turn.

Row 17: Work 1 sc in each of the 16 stitches. Chain 1 and turn.

Row 18: Inc, sc in the next 14 stitches, inc (18 stitches total). Chain 1 and turn.

Row 19: Work 1 sc in each of the 18 stitches. Chain 1 and turn.

Row 20: Inc, sc in the next 16 stitches, inc (20 stitches total). Chain 1 and turn.

Row 21: Work 1 sc in each of the 20 stitches. Chain 1 and turn.

You’ve now completed the basic triangle crochet! You can continue this pattern to make a larger triangle, or finish it here.

Adding an Edging to Your Triangle Crochet Pattern

For a more finished look, add an edging to your triangle crochet by working a round of single crochet around the entire perimeter:

After completing your final row, chain 1 and continue working sc stitches along the straight edge
When you reach the first corner, work 3 sc in the corner stitch to create a smooth turn
Work along the sloped side by making 1 sc in each row end (there should be 21 sc along this edge if you completed 21 rows)
Work 3 sc in the point (the second corner)
Continue with sc stitches along the other sloped side, again working 1 sc per row end
Join with a slip stitch to the first sc of your edging round
Fasten off and weave in your ends

Troubleshooting Your Triangle Crochet Pattern Edging:

If your edge looks wavy, you’re working too many stitches – reduce the number
If your edge curls inward, your tension may be too tight – try looser stitches
Each slanted edge should have approximately the same number of stitches as rows in your triangle

Triangle Crochet Pattern Variations

Once you’ve mastered the basic triangle crochet pattern, try these variations:

Sharper Triangle Crochet Pattern

For a taller, narrower triangle, increase the number of rows between increase rows:

Row 4: Inc, sc, inc
Rows 5-7: Sc across (3 rows of just single crochet)
Row 8: Inc, sc ×3, inc
Rows 9-11: Sc across
Continue this pattern of increasing only every fourth row

Wider Triangle Crochet Pattern

For a wider, more obtuse triangle, increase at both ends of every row:

Row 3: Inc, sc, inc
Row 4: Inc, sc ×3, inc
Row 5: Inc, sc ×5, inc
Continue increasing at both ends of every row

Triangle Crochet Pattern FAQs

What projects can I use a triangle crochet pattern for?

Triangle crochet patterns are incredibly versatile! Use them for bunting, blankets, shawls, scarves, and as building blocks for more complex shapes like diamonds, hexagons, and 3D objects. They’re also perfect for creating interesting geometric patterns in garments and home decor.

Can I get sharp corners with a triangle crochet pattern?

The nature of crochet creates slightly rounded edges, but you can achieve sharper corners by blocking your finished triangle. Pin the corners firmly when blocking to create more defined angles. Single crochet typically creates the most defined corners in triangle crochet patterns.

What is blocking and why is it important for triangle crochet ?

Blocking is a finishing technique that shapes and sets your crochet work. It involves wetting or steaming your piece and then pinning it into the desired shape until it dries. This process helps even out your stitches, straighten edges, and create crisper corners. It’s particularly beneficial for triangle crochet patterns and other geometric shapes where precise angles matter.
