I've just started these, too. I don't have the sticker maker, so I just modge podged the image to the cap and then modge podged again over the image.
Once dry, I pour the et lite over them. After a few minutes (like maybe 5) I use a straw to blow the bubbles away. Be careful, though, it doesn't take much to blow the bubbles away! If you do it too hard, you'll blow the et lite right out of the cap. (Don't ask me how I know this!) I move the straw around in a circular motion around the cap...it's funny how they just disappear!
hope that helps some...I don't know what to tell you about the stickers
