Well I have some good news and some bad news. It's always best to start with the bad news.
Bad news: It seems I've miscalculated stitches needed for Apollo's sweater. This may also be an understatement. After knitting for a while, gauge changed and magically grew from 4.5 stitches per inch to 4 stitches per inch. It's also possible I'm seeing things. I will measure again later. I also transposed one of the numbers when measuring his pre-existing sweater, making it much larger than reality. However when I do the math I still can't figure out how I came up with 243 stitches.
Apollo dared to pretend it was a hoola hoop!
Good news: All is not lost. I've only knit 5.5 inches. (Boo!) Ripping it out (Argh!) will stop me from knitting needles stitches, creating a huge sweater and will of course reduce the time it takes to make this sucker.
