You could do circles and other geometric shapes that repeat as you go out from the inside. You also alternate to make each snowflake unique. Pretty and inexpensive decoration.
Bottle of Boos. A great Halloween idea www.partyista.com. I am so doing this with my grandkids. We will be using stickers. Saw a lot of places where this was for sale, but no instructions. It looks much better with the etched glass.
Great reusable idea...but might tire your arm out halfway going up and then back down! Lol...the look is great!
