I finished knitting it and sewed it up roughly in ‘normal’ yarn, just in case, and it still doesn’t look right. It may have been the way I sewed it, so I have taken out the stitching to try again to see if I can get it right before committing to sewing with the actual yarn and hiding the stitches forever, sewn and knitted. I wish now that I had waited to knit the second slipper before sewing up the first. I could then have compared them for size pre-sewing up.
