I just loved Leslie Gordon's concept behind this e-book of children's hats.  Pre-k through 5th grade.  Each hat fits the age perfectly for your growing child.
 
Pre-K:  Bobbles for your toddler.
Kindergarden:  ABC's and 123's using a duplicate stitch.
First Grade:  A bright brim with a fleck pattern.
Second Grade:  A thinking cap with a rolled brim, stripes and the cutest pom-poms.
Third Grade:  3 color fair isle pattern maybe even use their favorite team's colors.
Fourth Grade:  Chic stripes that are easily woven through the knitting.
Fifth Grade:  Time for cables!

The patterns are sold individually OR as a collection.

Leslie has generously offered to give away the entire collection to 3 of my readers! If interested, please leave a comment before Thursday December 12, 9am EST and I'll have the random number generator pick three names.
