Shown here is a typical hole that might need patch repair.
Clean the hole by melting the ends of the twine around the edge of the hole. This prevents the twines from unbraiding. Count the meshes that you need to replace. Prepare a patch using Ultra Cross netting that is the same diameter and strength of the net needing to be patched. The patch should be two meshes larger in each direction than the cleaned-up hole to provide sufficient netting to overlap the edges of the hole. Clean the patch by melting the ends of the twine around the edge of the patch.
Lay the patch over the hole and lace it to the existing netting using appropriate braided twine, as shown in the illustration. Make sure to lace the crosses of the netting together.
Continue lacing around the hole so that you have at least two rows of lacing around the patch. The patched hole will resemble this illustration when finished.
