My 3 DD's just made their own ear hats last week - I recall thinking they ended up being a dollar more than the pre-made ones. I don't have any good pictures of them, but there were many to choose from. Youngest DD got a pink one with pink fur trim and the ears were both pink fur, middle DD got a pink lace covered hat with black ears that had pink prism like shapes in the 'mickey ear' formation themselves, then oldest DD got a traditional black one with ears that had fireworks on them. They had tons of options (from glow in the dark ones to character ones) and the ears just snap on (flaw here is that they snap off easy too). It was oldest DD's bday so they gave her name embroidery for free! Otherwise it was $7 I believe. They also have patches that they can iron on - one DD got a princess crown on the front of hers - I think they were around $3.50 each.
Regarding the make your own pins- the only think I saw was where you buy the pin base and add magnetic numbers, sayings, etc. - but knew that it probably wouldn't work for us - I was afraid of the magnets falling off - maybe someone can provide more detail on this.....
