I have a scarecrow and some movable flying spinners to keep the deer out of my garden. I learned that deer see blue and green so I created a blue and green scarecrow and blue and green spinners. The spinners are wrappers from Dasani Water Cartons (blue and Green) they are very sturdy and spin very well. I used a paper clip which I attach a fishing line swivel then another paper clip which I attach to a bent coat hanger. The weakest part is the swivel so I keep them handy. I keep the paper clip closed with electrical tape.
