HOW TO GRADE A ONE-PIECE SLEEVE.
When grading a one-piece sleeve we have to increase on both sides. When we have a one-piece sleeve complete, place it on a sheet of paper and mark all around from A, F, N. E and D to B; cross lines from A to D and from B to N. We also cross a straight line lengthway to centre of sleeve from F to C; increase from A to G and from N to M and E to K 1/4 inch; make a curve parallel from A, L, N and K, and from D to J and from B to H 1/4 inch. Make the outside lines so as to increase from G to H and from K to J. For all one-piece sleeves the system of grading should be followed the same way. This completes the grading of the one-piece sleeve.
