hi,
when i first read this i figure that be easy...lol.... but come down to it.... i could only find 2 and they were poor tutorials on making a cross from scrratch.... if you want that one search for PHOTOSHOP TUTORIAL GOTHIC CROSS ...
and then only found a few other tutorials that involves a cross but in those cases they used cutouts , they didn't draw the cross from scratch ...
this site has a tutorial on that on making a christian theme wall paper...
http://www.tutorialhero.com/tag-1-Christian.php now another idea for crosses .... and that is download a "cross" brush... there many of those avail and most free free... and many are of intricate design..... like
