This is a pattern inspired by Jinx’s butterfly from the series Arcane. You can use whichever crochet hook size / matching yarn as you prefer, although it will affect the final object’s size.

For references, I made two sizes:

• 2.5mm hook and Katia Capri yarn: 24cm butterfly (large)
• 2mm hook and Scheepjes Maxi Sweet Treat yarn : 18cm butterfly (medium)
