What a great summer yarn for this week! It's Bamboo Silk by Ella Rae. Eminently affordable for a silk blend yarn, even at full price, it's now 20% off. 22 colors available - see them at the website.
Otherwise, the specs should speak for themselves:
Fiber: 70% Bamboo, 30% Silk
Needle size: 7
This yarn will be on sale until Wednesday, July 15, midday.
