Well, I can!
My sewing project last night was repairing the frayed stitching on the toes of the shoe on the left for Madeline. The moccasin stitching held up for quite a few months of wear, but my first attempt to repair with dental floss didn't quite work out as well as I'd anticipated.
I ended up using some sort of fine cord (or maybe it's just thick thread) from the shoe hospital on Duckworth Street to do the job. I wandered in there with Madeline one day to ask if they sold thread for moccasin stitching, and one of the employees just gave me two feet of cord for free! I was thrilled, and have to repay that debt by doing something nice for someone else when a good opportunity presents.
It's a different type of thread than what the manufacturer used - the original thread is much finer, and several layers are used. It kind of reminds me of fishing line because it's more plastic-ish than fibre-ish. I used a curved quilting needle for the stitching, and I'm happy with the end result!
