This craft was sparked by these but mine are WAY more simple.
You will need:
 4' Dowels I used 1/4" thick ones for .88 at homedepot
 Different Colors of thin craft foam I got a big pack of small sheets for $1 at dollar tree
Kids craft paint in a variety of colors $1 at dollar tree
Exacto-knife or hand saw
Paint Brush another $1 for the multipack at dollar tree
Glue-gun with clear glue
Cut each of the dowels to be 1.33' long and sand the cut ends to be rounded. Cut your foam into 3-4" half feathers (a half oval is OK) you will need 3 half feathers per arrow. Make fringe on the rounded edge of each of the feathers.
Your or your kiddo can paint the dowels. We made the rounded tips grey and the base of each yellow with various colored bands in random spots. Once the paint is try, hot glue the straight edge of the feathers to the non-pointed end of the arrows. Glue 3 one each at 90 degree angles from eachother. You can put 4 on each but I left one side "flat" because I intend to hang them on the wall somehow.
I ended up doing all the work on these and Bear pretends they are flowers or rockets but they are still tons of fun!! I cant figure out a good way to hang them because for some reason the 3M stickies dont work well on Bear's walls.
