I’m in the process of restoring a roll-top desk, and will be re-canvassing the tambour slats for the roll-top. The old canvas was put on with hide glue, and I’m planning to do the same. I seem to recall the addition of glycerine to the glue for some purpose–was it to keep the cured glue more flexible? If so, does anyone know what quantity of glycerine is to be added?
I tried a search and came up empty, would rather not leaf thru every issue of FWW on my shelf.
