I have used We Are Knitters “The Petite Wool”, which is classified as ‘bulky/chunky’ yarn of similar thickness – www.yarnsub.com is a great site which will help you find some compatible yarn depending on your location and how tight you knit.

This pattern is written based on using a “Bulky” yarn and can easily be substituted for say Malabrigo Rios and use 2 strands at once, with the same cast on and pattern provided here.

Super easy pattern to follow and easily adapted for all sorts of yarns
