While doing my prep for the weekend (so many fascinating things trying to side-track me! So many things I'd like to do more research about! So many questions remaining!), I stumbled across an open access online journal about Archaeology of the Low Countries. Sadly, this lovely little journal only had a few issues before coming to a stall, but the Journal for Archaeology in the Low Countries website might still be worth a visit for you - especially since vol. 2, published in 2010, includes an article by Chrystel Brandenburgh about early medieval textile remains.
