Mistress Þóra Sharptooth’s Viking Resources for the Reenactor has resources on clothing and textiles, personal display, food, etc. It has been one I have returned to a few times, though it has not been updated for several years.
If you’re not aware of it, the Viking Answer Lady is a wonderful resource for some general Viking Age information. It is hosted by a SCAdian, so some of the information is centered on SCA concepts (like heraldry and devices).
I came across this today:
The Viking Connection Apprenticeship Program (VCAP) provides an opportunity for selected students of Viking Age crafts to study under a skilled master artist in Scandinavia. The application round for the 2019 is now available by clicking on the link below. Submit your application by July 31, 2018. Applicants must have a current passport and be a resident of any of the following states: ND, MN, IA, SD, WI or MI. Following each apprenticeship, the apprentice will spend up to a year traveling to various events, festivals and workshops in the Midwest to demonstrate the recently-acquired skills. Dates will be posted as they are confirmed with each host site.
