g 10 ft indicia on an original prior art sock may end up being 6 ft apart after filling due to 40 shrinkage or any number between 6 ft and 10 ft specifically in fig7 the integrated visible stake placement indicia 44 in the compost filter netting 12 of a compost filter sock 10 is formed by a distinctly colored thread 35 e g an orange thread that follows a warp thread 34 not shown in fig7 for clarity and then inlays back and forth between two adjacent warp threads 34 at the appropriate intervals to form the indicia 44 warp knitting technology can easily and effectively add distinct visible threads at any location in the netting 12 as known in the art to form the indicia 44 but it is the linear stability that allows these to be added in a meaningful manner the indicia 44 also serve as a sock 10 length measurement tool for users and inspectors separate from stake placement it is anticipated that multiple threads 35 e g 4 8 would be spaced circumferentially around the netting 12 to form rows of indicia 44 such that the indicia 44 would always be visible to users regardless of how a particular sock 10 is positioned on the ground the compost filter sock 10 according to the invention preferably exhibits a radial stability wherein the circumference of the empty or originally manufactured compost filter netting 12 is at least 90 of the circumference of.
