Overall a relatively simple job - if you have a sewing machine and some experience with collars
The Material and construction have a lot to do with how the collar will stand. Many are made with the exact need built in. Check em out at a thrift store and you'll see what i mean.
The material in the replica you picked up looks light weight. A spring/summer weight as opposed to the screen version looks heavier to me, like a bottom weight/winter weight
The collar to me looks like 3 pieces. The 2 that make up the main body of the collar and the added quilted piece on top collar.
*Before you take it apart - take picture and take pictures during each phase of the deconstruction....especially if your not familiar with sewing or its order of operations.
-Open the collar up, a seam ripper will make life easier and make fixing mistakes easier as well
-add Heavy Weight Iron-on Fusible, Horse Hair Interlining or Buckram depending on how crazy stiff you want it to be - add this to the Under Collar and stand (if you have a stand) (Do not add Boning!)
-*Do not close the collar up yet*
-Find Material similar in color and weight for the top quilted piece (if possible)
-Pin the batting to the fabric and sew a series of evenly spaces lines (look like 1/4" to me) - Leaving the thread hanging off on the head and tails of your start and finish. And now its quilted.
-Now the attaching it to the this to the top collar requires a little bit of patience and pining, but is pretty much like adding another collar to the top collar. Youtube will save your butt here it's be a lot to describe with out pics to illustrate it all. But you take the quilted piece and fold back you seam allowance and sew it with a 1/16 seam. Look like the side and bottoms of the quilted piece are closed up on top of the top collar before the collar is closed and attached. Sometime it's just trial and error to see what works. But the superior edge of the quilted piece might be closed up with the top collar and the bottom collar, cant find any pics of that so...trial and error.
*You may need to unquilt the seam allowance area cause it doesnt look like it is in the ref pics.
-Once the quilted piece is attached closed the collar up and attach it.
That's my 2 cents - for whatever it's worth.
Have fun - bet it'll turn out great.
Alright - ***Edits***
*Found a pic and it look like the whole collar has 1/8 hem top stitch all the way around. The more stitching there is the stiffer and more body the collar will have.
