These red rose crochet flowers are the work of a Thai crafter / artisan. Her hame is Patty Nimo. These patterns are all available for purchase only (no free patterns, unfortunately, although we found something similar for those wanting a free pattern, below). The patterns cost in the range of $3 to $5 on the Happy Patty Crochet website.
