Die cuts are usually easier, but depending on the size of the sticker you can make it work. Use a blow dryer on the sticker while putting it on. This melts it just a tad so that it mold to the surface better. After its on and dry, it should return to its original state. Also, use a credit card to smooth it out as you put it on. Lastly, if there are any bubbles you can pop them with a pin and deflate them.
