Numerous craft websites have free knitted hat patterns, including AllFreeKnitting.com, KnittingPatternCentral.com and KnittingOnTheNet.com. Patterns are available at different difficulty levels and include both traditional and novelty hats.
Toddler hats can be knitted in a range of different yarns. Bulkier yarns with thicker needles knit up quicker than lightweight yarns. Hats are usually knitted in the round on circular or double pointed knitting needles, although there are some two-needle patterns available. Easier hats are made using garter stitch; more complex ones can be made using lace stitches or cabling. If using a different yarn from the type recommended in a pattern, make sure to use the same gauge.
