Free Crochet Shawl Pattern – Keyhole Striped Boomerang Shawl
This post includes affiliate links.
This is a free striped Boomerang Keyhole Scarf Crochet Pattern made with treble crochet stitches in a boomerang asymmetrical shape, as well as dk yarn.
Shawl Crochet Patterns can look so different, unique, and yet so similar. But some are very different and have a special feature to allow you to wear them in different ways. In fact, I prefer shawl patterns that are eye-catching and make you feel special and unique, more than you already are.
This unique striped curtain-like boomerang keyhole shawl is exactly that. It is shaped like a boomerang, aka an asymmetrical triangle shawl that has several keyholes on the long edge such that you can pull the short end through and ruffle it up and make it look like a curtain.
Boomerang shawl crochet patterns are super beautiful, yet unique and special that I designed several of them already.
This striped boomerang keyhole shawl is much easier than you might think though. It increases by 1 stitch per row, but to create the boomerang shape, you increase by 3 stitches on one edge and decrease by 2 stitches on the other edge.
The entire striped boomerang keyhole shawl is made with treble crochet stitches using 2 different colors using Lion Brand’s beautiful and soft Coboo yarn which they provided me with to make this amazing shawl for you.

Free Written Pattern for the Striped Keyhole Boomerang Shawl
Shawl Pattern Notes
This pattern follows a 2-row repeat with color changes as stripes. To make the repeat easier to write out and understand, I will call chains and chain spaces stitches.
Each row increases by 1 stitch.
I also did not use a Ch4 as a turning chain, but instead used the Alternative Turning chain as the first counted stitch of every row.
ATC = make 1 sc, *then insert hook into the loop close to the next stitch, yarn over and pull up a loop, yarn over and pull through 2 loops, repeat 1 time from * to have 3 stacked sc stitches.
Crochet Boomerang Shawl Pattern
Start with the color Mauve, Ch 10, start from 2nd ch from the hook
R1: [1 ATC, 2 tr], 1 tr in each st until last 2 sts, 1 tr dec, turn
R2: 1 ATC, sk 1 st, *1 tr, ch 1, sk 1 st, repeat from *, in the last st place [1 tr, ch 1, 1 tr], turn
Repeat R1 and R2
Crochet 1 row of Magenta after you crocheted 12 rows of Mauve. After the first color change, crochet 13 rows of Mauve, then 1 row of Magenta until you have 8 stripes (or less if you want to shawl to be shorter).

Crochet Keyholes to Boomerang Shawl
After 8 Magenta stripes do the following:
Crochet 8 more rows of Mauve (still repeating R1 and R2), then do the following row like this:
R119: 1 ATC, sk 1 st, *1 tr, ch 1, sk 1 st, repeat 4 times from *, **1 tr, ch 9, sk 9 sts, ***1 tr, sk 1 st, ch 1, repeat from *** 3 times, repeat from ** 5 times, 1 tr, sk 1 st, ch 1, 1 tr, sk 1 st, ch 1, in the last sts crochet [1 tr, ch 1, 1 tr], turn
Crochet 3 more rows: Repeat R1 and R2 again seeing the chains as stitches
Fasten off and weave in all the ends.

You can wear this curtain-like Striped Boomerang Keyhole Shawl Crochet Pattern by pulling the short end of the shawl through the keyholes of the long edge of the boomerang shawl.
