These "Hole Punch Paper Snowflakes" from My Homemade Decorations (http://www.my-homemade-decorations.com/traditional-christmas-decorations-hole-punch-paper-snowflakes.html#) are easy to make and would be a great addition to a winter bulletin board display to give it a 3 dimensional effect. They would also look "wintery" hanging from the ceiling, like falling snowflakes.
Make your own Christmas tree with discarded branches. Tie it together using wire so that it forms a teepee shape then add homemade decorations for a simple yet strking effect. It’s an easy, affordable, ecofriendly and elegant tree option.
