Hi Becky and Salmonmac,
The pattern assumes you’re left with 28 stitches after binding off the 2 lots of 9 and 2 lots of 3. For the next row it then tells you to knit 2 together across the row. The following row is the last and in that you knit 2 together across the row again, leaving you with 7 stitches, but following the pattern leaves you with 30 stitches at the point where you should have 28. I guess you’d just have to bind off the 8 stitches you’d be left with at the end, but someone on another forum suggested the first lot of stitches bound off should have numbered 10, not 9, which does leave the numbers right, so I have frogged back to where I had bound off the 2nd of the 3 lots of stitches and am taking it from there.
I did email the designer/s on the website where I found the pattern and one of them emailed back to say that here was probably some adjustment in the numbers for the large slipper that did not get carried through to the end and it got published that way and that she would correct it.
She also said that according to the directions I would end up with 9 stitches and to go ahead with those 9, but I don’t know where she gets the 9 from - maybe she had a bad cold too lol - which reminds me, I hope you 2 have recovered from yours.
