Yep, exactly that, roll a 3ft long 3-turn 60mm id tube using a 3ft x 570mm sheet of kraft. Cut it lengthwise along the line where the first turn starts and the last turn ends. Use the 3-ply sheet to roll the 3/4" tube. A metre of 2.5" od tube would`ve been a better fit (200mm per turn) for the 3ft x 2ft sheet but 60mm is all i had on hand.
Marking a line on the former makes aligning the sheet easy, attach it to the former with 2 small tabs of thin tape on the corners of the kraft sheet. Those points will become the ends of the final tube. Attaching the sheet to the former makes applying the glue easier, cos the paper is pinned down by the former and it has half of the 1st turn on it. You can roll the tube without worrying about aligning anything so there`s no delay or panic. The 3 x 2 sheet will take 15 seconds or less to roll onto the former.
