OK Charlee he measured them and they are so close that even with the magnifying glass we neither one can read the marks (and he just got new glasses) But the depth of each one is different. New Home depth is 3/8 and the Macy is 5/16. Don't go to to much work to figure this out because I will probably only use it for quilting. Would love to do FMQing with it but I figure there is not a foot for doing that.
