order right & left skirting sides?

Your comment is valid, but not very applicable in today's saddle market.  Most of the hides turned into saddle skirting in the US are steer hides.  No cow hides are being used for saddle skirting.  These steers are young... under two years.  No stretch marks and minimal difference between right and left sides.

 For most, the most important thing to remember is that leather isn't plywood and saddles aren't tool cabinets so you have to look and think while you work and remember that you are making a thing which has lots of different stress and stretch requirements (a saddle or some piece of equipment) out of a material that was part of a living thing a short time before and you must match requirement and material. Most will never be able to afford to sort their way to satisfaction but will have to look, feel, and think a lot to get the best job done. Learn all you can about the use that saddles get and the nature of cows and it will all help you make better stuff. Most of all IMHO be prepared to have a big scrap box with lots of stuff in it if you make very much good stuff.
