My friend and I have a button maker. We'd be happy to make HP-themed buttons in exchange for $5 donations to the red cross. We can make them in 2.25 in. or 1.25 in. sizes (1.25 is cuter). Just ask for what you want! (I'll include a picture of some of the ones we made when I can). There'll be S.P.E.W buttons!
Are there any fan artists who'd allow their work to be used for this purpose?
