I know there is a million of these out there but I designed my own anyway. I wanted one that was cheap and portable but was somewhat professional looking so my clients wouldn't think I was a total amature. This diffuser is designed for the Canon 580EX II flash but could easily be modified to fit any flash, or it may not need modification at all.

Things you'll need:

Posterboard (Black), or if you can get polypropelene sheets even better. ~$1
1 12x15" frosted cutting board (thin plastic, avaiable at most dollar stores)***
Scissors or olfa blade
Ruler & Protractor (not needed if you print out the template)
Electrical Tape (preferrably black)
Velcro with adhesive backing (or you can glue it yourself)

Optional: Glue, if you want to make tabs and glue it instead of using electrical tape

***If you can't find the clear frosted cutting board you can simply cut the same shape out of the posterboard then cut a small window in it and use tissue paper, velum, or even a cutout section of a white plastic bag.

Step 1: Supplies

Picture of Supplies
The image below shows the supplies you'll need, I forgot to put the velcro and the electrical tape in the shot though ;) Also the gluestick is unused in my version but if you want you can modify the project to glue it together instead of using electrical tape.

Step 2: Print The Templates Then Trace Onto Posterboard

I've included the templates in pdf form so you can cut them out and use them to mark the poster board.

When printing these make sure you disable "fit to page", these are designed to fit on a standard 8.5" x 11" sheet. I suggest measuring the pieces after you print them to make sure they weren't changed. The templates should measure exactly the same as the dimensions labelled on them.

Trace the front panel diffuser onto the cutting board. It may be a good idea to make a few ticks to show you the line to fold along as well (template shows the fold lines).

Nice. thanks, this gave me another thought. I've been looking at flash extenders (better beamer)(google). With this format, slightly modified for size, the plastic duo tangs and a cheap Fresnel lens available at most dollar stores, I came up with a very workable, good looking flash extender for nature photography. Great instructable.
WOW awesome diffuser! That looks so clean. Once I get a digital flash for my 40D i shall make one of these for sure. definitely going to add to my favorites. Great instructable!

Thanks for the comment Alvin, I've since gotten a little more ambitious and am working on come cheap (yet nice looking) softboxes. Once I have a streamlined approach I'll be posting it as an instructable. Oh also, I found some black plastic duo-tangs that would work great for this diffuser and look a little sleeker. They are available at any office supply store, I actually got mine at a $1 store. Once I remake one I'll post it as a followup.
