Wow, another week past already! It seems that when I post one of these questions every Monday, the weeks seem to just fly by, LOL!

What Am I?

1. I am one of those things which always has to be looked after and mended.
2. Generally I am long and narrow with square holes and am made by knotting ropes to form a mesh.

I'll approve all the guessing comments at the end of the day, so that everyone gets a fair chance to guess! Have fun!
