It may not look like much, but arranged in the order, it can look like this!:

But what if you didn't reserve a number and you need to change it! BAAAAM!!:

I just used the top file, cut them out and they easily arrange into whatever number you need. I used magnetic sheets from staples, they run through most desktop printers, which means you can take the file and color the numbers for instance if you have a white car, these exact numbers would not work. One sheet is good enough for two numbers (depending on how many pieces you need for each number) with some extra left over. If you want the full size file, just shoot me a PM with your email addy.
Let me know what you think!
***DISCLAIMER: I haven't used them in an autocross yet, I'm pretty sure they will stick well enough to not fall off, but I could be wrong. We will see on 9/15!!
