I have about 100 carp sacks, mother in law made the (yes, my mother in law !).
Used old curtains (you know the white see through ones usually at the back) - MAN I realt do not know these domestic home stuff. But you know which ones I mean?
1,5 meters by 600cm deep. Cord and clip - total cost R25 each (if that). They weok perfectly - and believe me when I say I take carp sacks to the extreme. Yeah they get dirty wit hte mud etc but they not there to look "nice" they there to hold fish.
