Ideas for living history activities for studying Vikings?

This year, I'll be teaching  Hands-On Medieval History. I'll have various classes, spanning Kindergarten through 8th grade. My goal is--kind of like with SkIP--to teach as many cool historical skills as possible. I had wanted the kids to carve soapstone molds for me to pour pewter into, so they can cast metal like the Vikings did. But, the more I look into it, the more expensive it is seeming. Most of the kids who signed up for my class really wanted to learn about Vikings, so I'll spend a few months studying the Norse.

So, I need some other ideas for Viking crafts. Something boat related would be cool, but what? Maybe something related to Norse mythology (*note to self: research Norse mythology more*).

Here's what I've got planned for the year thus far:

Era	Subject	Activity
Fall of Rome/Early Medieval ~476-800
	Beowulf (stories before writing)	Write an Alliterative poem
	King Arthur	Quill & Ink (Medieval European writing)
	Eastern Roman Empire	Make a mosaic (hopefully with actual stone!)
	Ancient China?	Sand casting by having kids make chocolate castings in brown sugar
	Islam & Islamic Golden Age	???
	Charlemagne/Vikings (800-1066)	Make a drop spindle
		spin wool yarn
		dye wool yarn
		Carve soapstone welding sticks with runes
High Medieval 1066-1300
	Norman Conquest & Crusades	Design a coat of arms
	Robin Hood	Paint coat of arms
	Crusades	Design a seal
	Magna Carta	Write a medieval document (law, letter, decree)
		Color wax and use yarn to make a pendant seal on medieval document
Late Medieval 1300-1492
	History of Paper/Parchment	Book Binding: Make Paper
		Book Binding: Sew signatures
		Book Binding: Make feather paint brushes (finish sewing signatures)
	Medieval illumination	Book Binding: Brainstorm/sketch illuminated letter/story
		Book Binding: Apply cover
	Medieval pigments	Book Binding: Paint Illuminated Letter with egg tempera
		Book Binding: Gild Illuminated letter
		Book Binding: Design cover
		Book Binding: Decorate Cover
	Medieval food & Medicine	Plant a medieval garden?
	Marco Polo	Make a map
	Henry the Navigator	Navigating with Mariner's Quadrant
	Christopher Columbus	Make a medieval ship from clay
	Silk Road	Silk Road Trading Game

(The High Medieval Era still needs organization. I'm going to cover the Genghis Khan, Canterbury Tales, the Black Death, the fall of Constantinople, etc. But, I'm still figuring out how I want to organize that section of the year. I'll probably just do "general medieval life" stuff, followed by historical events. I'm not sure, though.)

Medieval subjects I haven't manage to cover: Warfare, castle building, medieval trades, more I can't think of.

I really want to do something cool and epic for Vikings, and I know making spindles isn't "Viking" enough. Any ideas?

Hand manipulated weaving was big with vikings.   Warp weighted loom was common, but the coast salish weaving frames have the same technique but easier to transport and set up.
