i was nervous about doing this, i really wanted it to look good. i looked around at my cases to try and figure out what areas i wanted covered, then i measured everything (several times). i then created a new Pages document and laid out 2* 8x11 pages with boxes the size of the areas i wanted to fill. i laid them out the best i can to try and take advantage of the sheets the best i could, getting the most use out of them. i needed an online tool to help me convert ruler measurements to decimal measurements and back. after i figured out what shapes to use, how many, what sizes they should be, and how to organize them on the pages, i then took an 8.5x11 paper and clipped it to the 3m page. i drew out the line where the 3m page ended, so i can know how much space i had, as the normal white paper is bigger then the 3m paper. i then unclipped the 3m paper and proceeded to use a ruler and a pencil to plot out all my shapes as best i could. i used dots every 1/2" or so to mark distances, and then i use the ruler to give me complete lines going along those dots.
i then double checked all my measurements, and clipped the paper back to the 3m sheet so that everything was aligned. i used a cutting board from the kitchen underneath the sheets, and then took an exacto knife with a new blade, and proceeded to slowly and carefully cut along all the lines. the dots that i used early to plot my lines helped a lot. just like when on a motorcycle going through a long bend, you focus and keep your eyes ahead of you through the bend, thats how i cut. i concentrated on every next dot and my hand followed (instead of concentrating on the line where i was).
after all the cut outs, i then cleaned my case with running alcohol pads in the areas i was going to apply the stickers. a lot of good dirt came off, and i learned thats a great way to clean the case. i placed the stickers on while they still had the backings on to see how they fit. some of them i had to trim down a little. applying them was easy, bubbles should not be a worry. just be careful, and then smooth them out with your fist.
i put reflective stickers on the backs of all my cases, and the sides. i think they came out great, and i have a little bit left over that ill apply to some small areas on my bike.
