Yes, dinos can be cute and cuddly when crocheted with a soft blanket yarn and a big hook. I used a 9mm, I hook. Of course this meant that I had to adapt patterns.
The hat follows the standard pattern for hats in the round
Simply make a magic circle, add 10 double crochet stitches into the circle.
R2 a double stitch in every stitch
R3 two double stitches in first stitch, then one single in the next stitch. Repeat all around
Row4 2 double in first stitch, then single stitch in the next two stitches and repeat all around
R5 single stitch in every stitch. Repeat R5 till hat is big enough for your child.
Do not fasten off but crochet 10 for ear flaps and turn. The ear flaps are ten stitches wide. Each row I decreased at each end till I came to a point then continued by chaining 20 for the tie.
Make a magic circle, 6 single stitches . Follow typical first two rows of increase but add a single crochet row between increase rows.
