I recently received some beautiful yarn that was something totally new to me, Hikoo CoBaSi. It's a blend of cotton, bamboo, silk and elastic. The yarn looks very tightly spun when it is in the skein. I had 2 skeins of chocolate brown and 1 of olive green:
I have one skein of the brown left and I'm tempted to order another skein of a different colour, maybe pink, and make a pair for myself, but I'm still on a yarn diet!
