Great site for diverse crochet stitches.
What caught my eye was the colors involved in this sweater, reworking it into crochet, multiple techniques could be utilized in order to create its' own effect! >>found here.
I actually just purchased this shade of lavender, planning in a few projects time to start a crochet sweater and this item is definitely pushing me to want to create it now! A crochet technique utilizing the faux cable stitch (a tunisian stitch or using a front post triple crochet cross stitch) would be perfect for this project! >>found here.
Love love this hot pink sweater, it is already on my to make list. I believe a basic crochet stitch, such as a HDC (half double crochet) or SC (single crochet) would fit this technique that was created by knitting. >>found here.
