I unpinned and trimmed 3/4″ off the upper – all the way around except for the heel, which I had already sewn.
I re-pinned and then stitched, using a walking foot – which was a bad idea, it didn’t like the bulk, especially at the gathered bulk in the toe area.
I still think that the booties are too big, but I’ll wait and see how they fit on Audrey. I would like to inset some cuff material and make them into pull-on slippers. I have some fake suede for bottoms and maybe fleece for the uppers, with a cuff for snugness?
