Thread Theory Haslam Hat

Buy the Haslam Hat sewing pattern from Thread Theory. The Haslam Hat pattern is an incredibly quick sew that produces a wonderfully cosy hat. This versatile, gently square-topped beanie features multiple design options and sizes. While most adult heads will fit the middle size, smaller and larger options are also included.

Choose between ear flaps, a classic beanie hem band, a yarn pom pom, and fun fleece tassels. This design can be sewn in many fabric types and is a great way to use up scraps of fleece, old sweaters, and soft knits.
