Yes I managed to knit a pair of slippers, my other sister in law from Vernons previous marriage always calls me her sister in law and she has very swollen feet and cant buy a pair of slippers. These were very hard to knit as I had trouble with a nerve in my shoulder blade at the time, plus I had a lot of pain in my hands when I knitted it as it is very thick and heavy.
They were knitted with two strands of Big Value chunky wool by King Cole, colour was called Heather. Then to add height I added a top piece which I finished off with a picot row, The flower was a water lily pattern from the book 20 to make knitted flowers I had some left over wool from another project long time ago so I have no idea who made it, and I added a bead in the middle.
This is a picture of her foot yes it really is a big foot, I stuffed a sock with small balls of wool to get the shape, it helped me to knit and get the size right.
I put on the bottom a non slip piece of rubber with a used blanket stitch around. I just they fit.
