Core Tech,
The term "Gingerbread" refers to the decorative carvings and figures around the ship. In Wasa's case, these carvings and figures were painted in very elaborate schemes instead of simply being painted in gold leaf.
Shrouds attach near the platforms, or tops, not the yardarm. Actually, they are rigged through the "lubber's hole" in the tops and run down the other side. They also attach near the crosstrees on the upper parts of the masts. If the kit contains injection-molded shrouds and ratlines, I would consider throwing them away and rigging them myself.
There are many terrific references that really help me, even after building sailing ships for over 50 years. These are:
1. Ship Modeling from Stem to Stern by Milton Roth.
2. Historic Ship Models by Wolfram zu Mondfeld.
3. The Neophyte Shipmodeller's Jackstay By George F. Campbell.
4. The Rigging of Ships In The Days of the Spritsail Topmast, 1660-1720 by R.C. Anderson. This one would be particularly helpful for rigging the Wasa.
5. The Art of Rigging by George Biddlecombe.
I hope that this helps!
