It took me an hour to do the first 2 bindings on 8" mug rugs. The next 4 took an hour and 15 minutes. I am pretty particular about how it looks and still feel that they need a bartack in every folded mitered corner of the binding. I have seen the fabric pull out of a folded miter after washing so it is necessary. I hope I can speed it up to 15 minutes for each by the time I finish the whole pile of them.
