Shoutout to the woman at the Syracuse book fair who showed me a sewing frame trick
I was at the book fair in Syracuse last month and a woman running the booth next to mine showed me how to keep signatures from slipping on the sewing frame using a strip of scrap leather under the cord. Two weeks later I rebound a 400 page book with zero shift, and my old method never got it that tight. Has anyone else tried leather scraps like that or do you use something else to hold the cords?
