The title gives it all away...
a clean pickle jar (or any jar really)
star shapes (I used a 2" punch)
I attached the stars with glue dots.
For the purpose of the picture, I used a handful of the gazillion straws I have.
Add some sand/rice/rocks and a candle...you've got a great little festive light!
Several jars lining a sidewalk would be really cute too!
