I looked at that link but could not find what I was looking for. The stitch looked like a popcorn or puff type stitch and the slipper looked just like a basic slipper...like she worked it in a square and gathered the toe and then closed part of the top and the back but was a puffy type of stitch rather than a straight stitch. She learned the pattern from her mom in Canada.
I've looked all over but can't find this stitch and I asked her, but she's older now and I don't think she remembers.
Thanks for your replies.
