Disagree with Flem...4.85 min
Bue I lay out a sheet of material 72 " long (Cause thats the length of my form) by whatever width I want to prep then use flat aluminum straight edges 1/2" apart and spray with a 3m adhesive. I leapfrog this over ending up with 2" strips of material after I cut down the middle of the adhesive with scissors.
The glue edge on both sides of the strip hold the material intact from fraying. Ill add this to my layup with a roller and like flem said make sure your bowsnot is warm to promote better wetout.
You do waste some material this way so maybe Ill try Flems method using a rotary cutter.
Hope that was clear as mud Lol
