Ugghhh! Such a Dork am I..... So, I sat down to start the sleeves for the Carlito Cardigan, content that things were progressing nicely. I open my case with my needles looking for my 4s when I notice that my 5s aren't there but my 6s are. "Wait didn't I just knit the back of my sweater with my 6s?" The scream was blood chilling as I realized that I had knit the entire back on 5s and not on 6s as the front. A glistening tear rolled down my cheek as I realized that I would have to redo the entire back. But then I set the pieces out and looked at them and I can't see a difference. So, no ripping and starting over. I'm guessing that the width of the back my be off a bit and I think I can compensate for that with blocking.
