The Thing 1 and Thing 2 hats as well as the Cat in the Hat hats came from my local School Box teacher store (thing 1 & 2 hats) and Michael's craft store ( cat in the hat) .
I made a shirt for my DD in celebrations of Dr. Seuss' birthday. It was made with heat vinyl. The circles were cut from George & Basic Shapes. The wording was cut from Lyrical Letters. Check out her socks. They were purchased at the Dollar Tree at Christmas.
That day I also gave away as prizes theses m&m stix, cat in the hat erarsers, pencils, and some other misc. goodies.
