More progress.  Here's the beginnings of the second border strip on the left:

It's denser and less delicate than the central motif or inner frame.  With luck the contrast should work out.  What you're seeing is a bit more than half of the original motif.  Remember that I'm doubling the width, so this works out to a bit more than a quarter of the final as I will be working it.   Note the upside down curlique along the edge.  When I mirror the strip longitudinally that curlique will be right-side up down the center, and will merge its left and right halves to become a sort of fleur de lys.

Found in Russia

Thank you to Kate from Somerset in the UK and to Lisa (blogdogblog) Young, both who sent me to the Russian website I was searching for (best viewed with your sound off).  The English translation is probably machine-generated, but the mitten designs speak for themselves (click on the Knitting link in that site's left margin). 

One thing I remember that's not there anymore (and I may be conflating two different Russian websites) was a series of traditional counted patterns for cross stitch and pattern darning, done in black and red.   While the bulk of this site is a commercial one dedicated to cross stitch, machine and punch-needle embroidery, the site I remember offered these traditional motifs free for the download. 

A feature of this site that's worth visiting though is the recipe section.   Click on the "I invite you to dinner" link and be prepared, both for foods enticing (and a few a bit suspect), and for the trip into a world of amusing translations.   While I won't be making "Pancakes with Liver" any time soon, "Meat in Pots"and Beshbarmak both look good.  Think puzzle/creative though to decode the translations.  For example, "laurel sheet" = bay leaf.
