The local temps here is Southern Ontario, Canada is still ranging in the low -0 C, but we crave Spring. Hats made of Roving spun yarns is still appropriate. Patons yarn and others have made them available in our stores. I prefer the 100% wool, although synthetic yarns are also available.
Here are a couple of hats using the Roving spun yarns AND some photos of a local Spring Bulb Show.
