The blue ribbon around the top of the dress IS a correct Viking device, but it's executed incorrectly and badly. There were two blue ribbons around the bottom of the dress, too; and the side seams were also all embroidered.
I took all that work out. All of it - I made the dress completely naked. I didn't track the hours it took me to remove it all, but I spent somewhere around 5 evenings carefully picking out all the stitching so as not to damage the fabric. Probably about 20 hours.
To replace the embroidery across the top, I opted for a trick we know the Vikings did use in their embellishment of the tops of apron dresses: stitching a strip of imported cloth, often silk, as trim around the top of the dress. In this case, my "silk trim" is a soft rayon strip cut from an old sarong. I considered layering it with a silk ribbon underneath or something like that, but I really just loved the way the sarong fabric looked with the black on its own. I fully intend to replace this strip with real silk if any real silk ever happens to me.
I also took apart the long, flat straps and made them into looped straps instead, which is correct for an apron dress based on loops we've found attached to brooches. I also like they way they function better: they're easier to use, and once they're affixed to the dress, don't require any adjustment. My straps came out a bit thicker than I wanted them, but that's okay - they look just fine and they work great.
There: all finished. The new design is simpler, but I like it much better than all that ridiculous embroidery I had going on before. I love that this dress is full length - I prefer a long apron dress.
And I really love the green and black (the color shows better in the previous picture, sorry). That came out better than I'd pictured. I have a ton of the green rayon sarong scraps left, too - I may use them to line a new Hedeby bag I've been thinking about making.
