I used a very soft and sturdy wool blend for this project but my testers also had luck using Vanna's choice and you could even use Red Heart Super Saver, Red Heart with Love or I Love This Yarn for more affordable choices! Just make sure you match gauge by adjusting your hook size if need be.
And be sure to let me know if you like the pattern because if there is interest I'll be designing adult sizes as well! From small women's to extra large!
