Blank Skin Template?

Is there a blank template out there somewhere for making one's own skins? Ideally one that doesn't take paid software to use?

I have an inDesign file that I can lend out to anyone who'd like it.

Fonts used: Yataghan, Fontin, Fontin Sans (all available free online). Various ornamental elements in: Wingdings, Wingdings 2, Webdings, Type One Embellishments (I know! So many! I didn't realize how much of a barrier that would be at the time!).

Email me at mcdaldno, which is a gmail account, and I can set you up.

Dang, Adobe doesn't kid around with the price tags of their programs, do they?
