Halo is a lace weight brushed Suri Alpaca. While it looks like mohair, it has amazing softness with none of the itchy-ness that you might find in mohair. Suri alpaca is very rare and very lustrous and is perfect for lacy projects. Each 50g ball contains an amazing 514 yards. You can achieve a wide range of gauges on a US #4-8 needle and beyond.
