This design was inspired by a custom Birthday request I received from Isla Dream Prints. She needed the perfect sparkly mermaid tail for her daughter’s 5th Birthday photo shoot. What a beautiful mermaid princess she makes! For her gorgeous white and mint mermaid blanket I used 2 strands of Bernat Premium in white sparkle, and 2 strands Impeccable by loops & Threads in Skylight.
