This pattern has been published in Russian language “Vesta” magazine, issue 2010#6(181) and can be found on page 34.

The magazine states (as it usually states on the pages for knit or crochet patterns) that the “materials have been prepared for publication by Nadezhda Proskurina”, whereas it is not entirely clear whether Nadezhda Proskurina actually designed the item or just wrote the pattern instructions.

Under “additional materials”, 4 gold-colored buttons are listed in the magazine.

Gauge is not listed, albeit the pattern states “don’t forget to make a swatch in pattern stitch and compare it to your own body measurements”.

Other than that “cotton crochet thread with a yardage of 420 m / 100 g” should be used, the magazine contains no further recommendations for a specific yarn.
