Write the person's name on one side. If you're not confident that you can do it straightly or evenly, make it obviously off-kilter, in a whimsical way. In other words, you would write "Linda" with the L low, the i higher, the n lower than the i, etc. Embrace your inner whimsicality, as I did here. Yes, embrace it and then release it upon yon Christmas bulbs.
On the other side, I made snowflakes by drawing a line, then drawing another line perpindicularly intersecting (I knew geometry would come in handy someday!) the first line. Draw two more lines to make your figure look like a pie cut in wedges. Then just make little lines coming off the main lines slanted. I added white dots on red flakes and silver glittery pain from a little bottle that you squeeze.
The paint dries really fast. In the clear bulbs, I added sparkly snow inside the bulb. Also, if you use clear bulbs and make a mistake, you can use an SOS pad and lightly scrub it off and simply start over! You can't do this with the frosted ones, though, because you'll scrub off the frosting.
Here are the ones I made:
