My knock-off version of Anthropologie's Crochet Spliced Loop ($58)
My version cost me 50 cents for the turquoise fabric which was a thrift store scarf. All other materials were scraps that I had on hand.
To create this scarf you basically need 2 sections of fabric (in mine, the pink section and the turquoise section), made by sewing right sides together, turning, and finishing the opening. My fabric sections were each approximately 9" wide by 20" long (finished). Then connect the fabric by adding a blanket stitch and crochet sections. I used this mesh crochet pattern.
I know these are pretty vague instructions so just leave a comment if you have any questions.
