I photographed this beautiful Blue Morpho Peleides butterfly at Amazonia indoor rainforest in Scotland. They are bred in captivity but have a large tropical glasshouse to live in. One escaped into the gift shop while we were there but was successfully shooed back home without spending all its butterfly coins on a plushy(!)
It's a superwash treated 4ply sock yarn that's soft and smooth with 75% bluefaced leicester wool for softness and warmth and 25% nylon for strength and durability. It is suitable for approximately 2-3mm needles. About 420 metres per 100g skein.
This yarn is presented as a skein. If you would like it caked then this adds 24h to the dispatch time and costs £2. You can purchase this service here:
