Setting the material into place

Time to do,  I finally found the right metal wire to use with the 2 faced lacing kit.  I think that the ratio 2 faced lacinig and the wire are perfect:

Now, I will have to put that to practice.  I have to shape the wire to the desired shape.  I do not know if it will be easy or end up as I like.  The second problem: will it be easy to lace the 2 faced lace with that shaped wired?  I do not want to destroy the shape of the wire as I do the lacing.  What I think is not the same as reality.  I am a bit affraid to the reality and that it will end up badly.
