I recently knit Jared Flood's Habitat using his yarn, Shelter. The thing that bummed me out was the way it came out a bit short. I've already ripped it back once, and am not up for any more ripping. So my plan is to add some length to the 2x1 ribbing by knitting a separate brim, removing the cast on row on the hat, and grafting the two pieces together.
The only trick is figuring out how to execute the grafting. I love kitchener stitch, but ribbing is a lot harder to read, as are the newly revealed bottoms of the stitches. Has anyone had any success in such a venture?
