Hi Karina!
Oh, you reminded me!

I remember thinking about implanting one vine, two leaves and one flower into the RIGHT FRONT SIDE. Oh gads. I don't know. I haven't quite wrapped my mind around modifications yet.
Hood/no hood? Fancy-work hood/plain seed stitch hood?

Collar? Zipper? Clasps? Buttons?

Plain Right Front/Fancy Right Front? Side to side cuffs/ribbed cuffs? Plain seed stitch sleeves/fancy-work sleeves?

Inside-out seams/conventional mattress seams?

Pockets/no pockets?
The more options & modification I see, the more I lean to knitting the entire pattern AS SET FORTH by the designer!
First to knit: SLEEVES>
I will make the cuffs as per pattern. I like them and I think they dress up the sleeve. Her cuff is classy. No further embellishments or designs on the sleeves. Plain seed stitch as per pattern.
Next to knit: LEFT FRONT>as per pattern
Next to knit: RIGHT FRONT>decisions need to be made regarding
1) chart 'design elements' incorporated into it (or not) and
2) buttonholes (or not)
Next to knit: BACK>as per pattern
Last to knit: HOOD>decisons, decisions

I'll think about the HOOD as I knit the other parts of the coat first.
