The Ariel boho crochet summer cardigan is an easy light and airy summer cardigan. Wear it over a tank top with simple jeans, it instantly uplifts your outfit. Long with lots of drape, it’s perfect for a summer stroll on the beach.
The Yarn
For this boho summer crochet cardigan, I choose to work with Katia Summer Comfort. It’s a sport weight yarn with a chain construction which gives it this great airy stitch definition. I used a bigger than recommended hook to give the cardigan extra drape.
It’s available in 16 gorgeous trendy colors. For this sample, I used their coral (68) colorway but I can easily imagine the cardigan in any of the other colors.
This yarn also has a special antibacterial treatment that avoids mold or bad smells when the item is wet. This treatment makes it great for beachwear. The cardigan easily doubles as a beach cover-up thanks to this special property.

The Crochet Cardigan Construction
The boho crochet summer cardigan is worked in 2 long panels sewed together. Each panel is worked lengthwise in rows back and forth. The panels are then folded in half and sewed together along the back and on the side (leaving a wide opening for the armholes).
