Oh wow. o: I didn't even know they sold things like that and had those kinds of stores. I have to look into that sometime! If I can't find it though do you have an ebay or paypal? I would totally buy these in a heartbeat.
[link] I used something like this and glued on ribbon, the solly symbol I painted on to a button with a paint sharpie and there are additional buttons. The hat I bought from the local store was ~30 and supplies were like 7 on top of that. I'm a terrible painter and its a pretty easy project so I think you could do it.
