If this little guy loves dinos, he will love it! Our 2 grandsons, aged 4 & 6 still love them and know all the proper names of those I never even heard of. I had already made 2 Elizabeth Hartman patterns: Fancy Forest for the 6 yr. old, and Awesome Ocean for the 4 yr. old so know well the amount of effort and organization this took for you to complete. You did a marvelous job and he will be "over the moon" thrilled.
