You will need the amounts listed in the chart for both lining fabric and exterior fabric. In many cases you will be able to cut two hats from these amounts; however, you will need these minimum amounts in order to make one. 

If  the child measures exactly to a size - for example the child has a 19.5” (M) head measurement, I would recommended sewing the next size of 20.5” (L).  If using thicker fabrics such as fur or sherpa and the child’s head measurement sits at the upper range of the size you are making, you may need to size up.

 

Suggested Fabrics

Avoid using thicker/bulky fabric for both the exterior AND the lining as it will be very thick to sew, unless you have an industrial machine. This pattern is designed for woven fabrics; however, it has also been made from knits during testing with good results. 

Exterior:  Wool. and wool blends, medium weight cottons, corduroy, denim, canvas, flannel, suiting fabrics, velvet, wool felt, fleece, or something similar.  Woolen blankets and felted woolen sweaters are also suitable although you may need to consider pairing with a lighter lining. Quilting cottons, linen, lightweight denim or chambray are suitable if you are quilting a layer of batting for extra warmth.

Lining: I like to use organic cotton sherpa for lining.  Any soft fuzzy fabrics can be used such as flannel, fleece, etc.  I try and choose breathable fabrics next to the skin if possible.  If you are wishing to use fur or faux fur, you might consider using these just for the forehead and ear/neck flaps.
