Does Anyone Know Where I Can Get Crochet Patterns For College And NFL Afghans And Other Items?

They can be adapted from cross-stitch patterns.  Here's on on-line cross-stitch "engine":

if the final chart is 1000 stitches or less, it's free.

Or use your own cross-stitch program, if you have one.  I run PCStitch under Windows emulation.  There are several free download software programs for WINDOWS systems.
