Almost finished with the top, Got to stitching the right border. Says to make (1) 6-1/2” x 66-1/4” border. But in my cutting instructions it didn’t mention to cut this length but to cut (2) 6-1/2” x 42 strip. I don’t see where it uses the 42 inch strips. Does it want me to piece my 42 together and trim it to 66 1/4”?
