These are the slippers that were worn out by DH and he asked me to fix and I was very reluctant to fix because the material is too hard to sew. DH still loves them because of the nonslippery material so he insisted I fix it. So after hours of handsewing and injuries from needles going all over my fingers and hands, I finally fixed them.
As you can see, I used the scraps of the upholstery material to cover the top and used bias binding to bind the edges. I hope they'll last for long.
