In the mean time ... Both pairs successfully completed. The yarn is Lorna's Laces Shepherd Sock Yarn. The patterns are from "Überlieferte Strickmuster Aus Dem Steirischen Ennstal" by Maria Erlbacher ( aka Bavarian Twist ).
Now, a few words for the so called yarn ... High quality and great to knit with. But on the other hand quite expensive to buy two skeins for a pair of socks when there are more color alternatives to invest. My critic is why they would not produce a reasonable skein weight so you need not buy a second one which will leave a significant amount of waste yarn behind. Because these yarns are variegated, there are not much alternatives to combine in harmonious colors in an other project. The skeins are less than 60 grams which is not enough for a short cuff/leg pair of socks. I would not have minded paying a couple more dollars rather than having have to end up knitting one of the pairs' toe from another brand yarn. You'll see the picture below. Not fun!
And for the first time - after all the knitting years - managed to break a bamboo DPN ... Luckily, one end was longer enough to handle the divided stitches. Shaped it up with a nail file :)
