I omitted to say that I still had to sew up the slipper - just on the first one - have started sewing it up and should be starting to knit the second one soon. I've done enough sewing to be able to try the slipper on and it's quite cosy.
I have the first slipper sewn up and have barely started the second - other projects have taken priority.
A couple of yarn ends managed to escape to the outside of the slipper. Since the fuzzy yarn hides the stitching so well, I'll have to try and push the ends through with a darning needle or something like that.
