Step 1: Find an image you want to use. I found an image for my blade barrier at:

Step 2: Modify the image and print it. I made no modifications. I just put the image in a word document, changed the margins in the word document, then resized the image just a little bit in word. Then I repeated the image 9 times (10 images fit on one page). Then I printed it on my color printer. I can give you the word document if you want it.
Step 3: Cut. A Blade Barrier in D&D 3.5 is 20' high, so I cut every 4 images (each image is about 1" so 5' in game terms). Then I found part of a paperboard box and cut it up, and taped an image to each side of the cut paperboard.
Step 4: I bought some Pathfinder Pawns this year, and figured the character bases would make great stands for my Blade Barrier wall and they do!
Now I just need to make a few more of them since our Blade Barrier walls should usually be much longer than the one shown in the picture.
Obviously you could use the same technique for a wall of fire, ice, or other.
You might even be able to use some of the dungeon tiles from various vendors for your walls.
Happy Gaming!
