The perforating tool four in four has 8 needles: 4 needles have been placed in a large square and 4 needles have been placed in the middle. The outer needles are slightly longer than the middle needles. This facilitates the re-perforating and/or reinserting. You can cut the 4 middle perforations to a cross, this cross will be slightly larger than the crosses made with the perforating tool 4 needle.
