The Triangle Trio Boho Vest is a free crochet pattern at Nana’s Crafty Home! Featuring a simple beginner friendly pattern made from 3 identical triangles sewn together!

I am so in love with this Triangle Vest! One of my favorite crochet loves is making triangle scarves. Honestly, I think I could happily spend my days designing and making triangle scarves! ?. If you are like me you are going to love making this pattern!

Made with 3 triangles sewn together – super easy and with very little sewing! The stitch is another go to favorite of mine – a half double crochet worked in between the posts to create a modern and sleek look. And basically, a 1 row repeat pattern!

This pattern is also available as an ad-free, printable PDF! You can purchase the individual pattern, or if you love PDFs, you might want to check out my Lifetime Membership. It’s an awesome deal! Never pay for one of my PDFs again!! (Or, scroll down for the free version!)

Another love for me on this pattern is the yarn I used — Lion Brand’s Comfy Cotton Blend.* When this yarn came out last summer and I worked with it for the first time in my So Long Summer Scarf I fell in love! So soft and comfortable! Perfect for wearables! The color options are also awesome with some recent additions to the solid colors so you will have a lot of color way options as well.

Child sizes are now available head on over to the free written instructions HERE. I can’t wait to see my little grand daughters in this cute vest!

The Boho style fringe on the bottom is completely optional but I feel it takes this vest to the next level! I made mine with a double knotted fringe which I think adds another special touch.

Scissors

Tapestry needle

Stitch Markers

Approximate finished size:

Small = 27” width x 20” length / Individual triangles = 20” tall x 26” wide
Medium = 29” width x 22” length / Individual triangles = 22” tall x 28” wide
Large = 31” width x 24” length / Individual triangles = 24” tall x 30” wide

4X = 39” width x 32” length / individual triangles = 32” tall x 38” wide

Gauge: 12 hdc rows (worked in between the posts see special stitch section below) = 4”, 11 hdc st = 4″

Abbreviations:

RS = right side
ch = chain
hdc = half double crochet
st = stitch
sc = single crochet
sp = space
sk = skip

Notes about pattern:

• ch 2 at beginning of each row counts as stitch.
• hdc is worked in between the posts for the entire pattern.
• Stitch count will increase by a count of 4 for each row.
• Resize:  3 rows adds 2” per triangle
• If your size triangle ends on a Color B color, I would recommend either doing 1 more row of Color A for each triangle to give more contrast at the join or doing your last row in Color A instead of Color B.

Special stitches:

The hdc is worked in between the posts.  Insert your hook under all three loops rather than just the two loops as usual.

Triangle (Make 3)

Row 1: With color A (RS) ch 3, sk 2 ch (counts as 1st hdc), (2 hdc, ch 2, 3 hdc) into 3rd ch from hook.  Turn (6)

Row 2: (Note:  you will now be working your hdc st in between the hdc post sts from previous row here and throughout pattern.)  ch 2 (counts as st here and throughout pattern), 1 hdc in between each st to ch 2 sp from previous row (corner), (2 hdc, ch 2, 2 hdc) in corner, 1 hdc in between each st to last st, 1 hdc in ch 2 from previous row.  Turn (10)

Fasten off.  Weave in ends.

Sew triangles together – see diagram below LEAVING ARMHOLE OPEN.  I used the mattress seam stitch.  Place stitch markers through both sides of triangle at top and bottom corners of middle & top of side triangles. 

Measurements:

Measure 4” (7” for size 2X – 4X) from top of each side triangle down, place stitch marker.

Measure 13” (10” for size 2X – 4X) from bottom of each side triangle up, place stitch marker.

This will create an armhole on both sides which will not be sewn.

Sew triangles together between stitch markers leaving armholes open.

Edging

With color A, attach yarn to RS of the bottom corner edge.

Ch 3, (counts as 1st hdc + ch 1), working evenly along bottom edge, *sk a sp, hdc in next, ch 1* repeat between * * to end, hdc in bottom of last row of hdc.  Evaluate as you go whether your hdc st are too close together or too far apart.  You want your edge to be even without pulling together or ruffling. See photos below:

Fasten off. Weave in ends.  

Attach yarn to corner bottom edge ch 3 (counts as 1st st + ch 1)  

Sk a space, hdc in next sp work evenly along bottom edge

Fringe

With color A, cut 4 lengths of yarn 16” long for each fringe.

Loop fringe through first ch 1 sp of edging, sk one ch 1 sp between each fringe.  

Double knot fringe by taking 4 strands of yarn from each fringe and making a knot.  Trim ends. 

Skip one ch 1 sp between fringe. For 2 end corners, you will take  all 8 strands and double knot with 4 strands from fringe next to it.  

Wrap strands from R fringe over 4 strands of L fringe, behind fingers in loop made.

Wrap end of R fringe around and down into loop, pull gently until knot made.  Continue working double knots along fringe, using 4 strands from each fringe to knot together.  Last corner end fringe will be worked with all 8 knotted to 4 strands of fringe next to it.  

With color A, attach button toggle at front of wrap at seam between two triangles.  Use ch sp from triangle on opposite side of wrap for button hole.  

To stabilize arm holes:

With RS facing, attach color A to bottom of arm hole, ch 1, sc evenly around arm hole, sl st to 1st st.  Fasten off.  Weave in ends.  Repeat for 2nd arm hole.
