Regia Arne and Carlos 6 ply is in the shop. I've used the fingering weight version of this yarn, and I love the colors and the durability. The 6 ply is a sport weight with so many possibilities, from socks to blankets to sweaters to hats to sweet baby sleep sacks.
Look at that big ol' beautiful skein. Just one of these will make a pair of grown up socks. Enjoy!
