44 in fig4 each commence in one embodiment in each wale and run along wales across courses as described it is appreciated that the 2 needle 3 needle inlay technique provides relatively lower widthwise stability of insect screen 100 as compared to the earlier described embodiment that employs the 3 needle 3 needle inlay technique albeit with a lower yarn consumption further 2 needle 3 needle inlay technique may provide stiffer horizontal or widthwise elements 105 h in insect screen 100 due to the shorter wale to wale yarn traverses included in inlay 33 additionally the 2 needle 3 needle inlay technique provides cleaner more balanced in width and length mesh or grid openings the embodiment described above utilizing the 2 needle 3 needle inlay technique also provides mesh or grid opening spacing of about 14 openings per inch other opening spacings can be produced for example employing an 18 gauge single jacquard machine and using 3 needle 3 needle or 3 needle 4 needle inlay techniques can produce insect screen 100 with an opening spacing of about 20 openings per inch it is appreciated that a wider inlay technique such as a 3 needle 4 needle limits machine speed relative to narrower inlays another example is employing a rascheltronic machine with 28 needles per inch or 28 gauge with a 2 needle.
