this is my one dumb question for the year. good thing i saved up for it

how do u kno if u spooled ure line correctly. ive heard that if u begin spooling ure line and stop and the line wraps around itself, u spooled it backwards. however, when i spooled my cabo 60 with PP the last time, i thought i had done it correctly and after several cast, i see a nest of line go through my guides. im not sure if this was because i overspooled or spooled incorrectly. any suggestions?
thanks again,
mike
