I have noticed that the fishing tackle actualy is more effective than the sewing for me and i think its due to the leveling up of the sewing skill as i remenber it being less effective when i was level 1, i would like other people to confirm this to as for me if i wanted to make say a moose hide satchel it would take 20 hours with a sewing kit and 16 with tackle, im level 2 sewing so if anybody else is more than level 2 id like to know the changes.
