Left over chicken wire what creative ideas do you suggest?

Take a big frame and frame the wire.... use it for hanging jewelry!

Some people use it by removing insert on paneled laminate doors and replace with chicken wire. You can also use behind picture frames then use mini clothespins and clip pictures on wire. That's a couple of things but lots more ideas available.

I built a missing door on a curio cabinet. It can also be used to fashion baskets and contain tall plants that have trouble standing up. Just place them around the plant and twist the end wires together. It is handy for vining plants either outside or indoors.

you could get a large used picture frame from a thrift shop, staple the chicken wire onto the back of the frame, hang it and use cute clips to hold photos, jewelry, whatever!
