I didn't see any instructions either but just break it down to small sections. Divide pattern into the sections with dark dividing line. Then in those sections piece (A) following the numerical order, then (B) following numerical order etc. Then join (A) (B) etc together to complete each of those larger individual sections. Then join those completed sections together. From the look of the pattern, the seam allowance between the larger sections in built in (I think)but someone tell me if I am wrong - I haven't made it yet.
I hope that doesn't sound too confusing. If it does, I'm sure someone else may be able to explain it more clearly.
