A small set where the accessory matters as much as the doll.
Who is in the set
Three in the Star Wars Young Jedi Adventures crochet doll set: Kai Brightstar, Lys Solay and Nash Durango.
Robes, not dresses
A robe hangs straight and open, which is harder to crochet convincingly than a skirt that flares. It has to fall without stiffening and stay open at the front without gaping, so it is worked as its own piece and set over the body rather than crocheted as part of it.
The small pieces
Each doll carries an accessory crocheted separately and attached — small enough at 6 inches to be fiddly, properly detailed from 10 up. If the accessory is why the doll appeals, choose the larger size.
Which size
10 inches for the three together. They are the same build, so mixing sizes here is unusually noticeable.
Where they come from
Three Jedi younglings training long before the era most of the films occupy, helping people across the galaxy in stories written for very young viewers.
Robes and small carried objects do all the identifying — there is no colour coding and no costume to speak of — which puts the weight on how the robe hangs.
