"Theme Packs" each include 10 Smalls that coordinate perfectly and are meant to be used together for a colour "melting" effect! Emma's Yarn picked the name Theme Packs because 1) they are located in the USA's Winter Haven, Florida home to Legoland and really close to other popular theme parks like Disney World, Sea World, Busch Gardens, Universal Studios, and a million more. It's a little wink to their stomping grounds and 2) the colours in the pack all suit a "theme" rather than perfectly fading or highly contrasting. All packs are dyed on Emma's Yarn's Super Silky base Fibre Content: 80% Superwash Merino, 20% Silk Weight: Fingering weight / 4 ply Meterage: approx. 740m total (10 x 20g small skeins)
