You can use any shape. It doesn't have to be a bunny. Just trace a shape or cookie cutter. This would be cute for any holiday, just use an appropriate cookie cutter to trace and cut out the shape, then whatever yarn works best for that holiday!
Traced around tie from knot to bottom. Taped money to it w/regular scotch tape. For back of tie just kind of cover it all up w/extra bills so you can't see the paper template anymore. My core teacher would love this
