Actually, I only have 2 others OTN at the moment. I'm waiting for my Knitpicks needles for one of them, and I need to buy (and dye) another skein for the other.
Im using 11s, since thats the largest I have. I did CO 1 for every chain in the larger size listed, and it's coming out about the same size as the smaller size. I did 2 rows of garter, and then switched to stockinette stitch. I'm slipping the last stitch in each row to make assembly and edging easier later. Right now I'm just trying to decide if I want to assemble as I go, or just assemble it at the end.
And yes, I'm using the same color... it does show the striping like the crochet, but I think the stripes will be wider than in crochet.
