I was wondering if anyone has tried to make the pattern for a convertible top in the Dec/Jan 2011 issue of Threads.  I'm trying to follow the given instructions and am wondering after havining matched the shoulder seams ectera they seem to of made one pattern piece for both the front and back.  No instructions are given as to which one to build the pattern from, front or back as they are both quite different.  I would welcome any help.
