My Retro Crop design is now available in Creative Knitting march issue which is on the newstand now. This is a really fun pattern to work with; very easy to memorize. I use cable fabric motif pair with 1 x 1 twisted rib. Since the cardi is meant to wear close to the body, and there is no shaping involve for the waist; hence, if you want to lengthy the cardi is just as easy as simple add a few inches to the body length. The sleeves are worked from top down; hence, to add length the sleeves just simply by continue knitting to the desire length in the cable fabric motif before switching to a smaller needle to work the ribbing. I do recommend to work decrease every 6 or 8 rounds to provide a more polish look.
If you have any question about the pattern, please feel free to contact me!
