I like making custom greeting cards for people. But I hate, hate, hate rotating the individual "pages" and lining them up correctly in programs like OpenOffice Draw.
Thus:
Real Cards Win.
Draw your pages in the graphics program of your choice (heck, even Windows Paint will do), then select and upload them. Real Cards Win scales, rotates and positions them correctly and generates a ready-to-print, ready-to-fold PDF file in which everything lines up just so. Doesn't get a whole lot simpler than that.
While I'm on the subject, I'd like to praise
ServerGrove for their excellent, cheap VPS web hosting. $19/month for full root access to a box of my own on which PHP 5.2.11 and MySQL 5 are already configured properly, with the gd library, the APC cache and everything else serious PHP geeks demand for performance. Can't beat that.
isitrainingout.com and
realcardswin.com are happily sharing a VPS at present. It's possible to secure so-called "shared hosting," but
it takes a lot of extra work, and at this price there is no reason to put yourself through it.
