Perfect for spoon flies. Well that is not very clear. Check Youtube and you can see a couple examples on how to tie a spoon. This is basically a very wide 1/2 woven mylar tubing. You can tie in one end at the back of the hook, push it back to expand the tubing to suit you, tie it off in front and coat it with Soloerez UV epoxy. Many times markers are used to color the backs or add interesting dots. These spoons are very popular for Red Fish.
