That hat is too cute! I'm trying it now in a varigated rainbow. How would you make it larger for a toddler?? I'm not sure it is working for me. :)

Are we talking about this hat? My 3 and 5 yr old nieces can wear it and I believe I did it with an H hook, sc's through the front loops only, and with Red Heart baby sport yarn. The directions say to do it in F. It's a pretty stretchy hat.
