About the crochet Summer Cardigan  

For this crochet cardigan I’ve used Concept by Katia Ultrasoft. This yarn is made of 100% organic cotton, but it looks like wool: it has a lot of volume, feels light and is very soft. Perfect for a summer cardigan! I’ve used color 55: I think the light salmon orange color is perfect for summer. The cardigan is worked top-down. By crocheting stitches in the back loop, a beautiful texture is created. I’ve used the net stitch at the bottom of the cardigan and sleeves which adds a beautiful detail. The cheerful flowers add a finishing touch to the cardigan.
