what do you use this feather for?

[DDRRedneck500]

well, a couple days ago i got a chance to go down to Gander mountain, which is the nearest store with a fly tying section (45 minute drive). and of course as soon as i saw the fly tying section, i immediately forgot my list of things i needed and among a couple other things got another ringneck pheasant skin. so i got home and was playing around with the new feathers (completely forgetting i still had one in a drawer right next to me) and ended up finding a use for everysingle type of feather on the skin -except one. those blue or green feathers along the lower back of the pheasant, not the biggest ones right at the base of the tail, but the smaller ones. i cannot for the life of me figure out what to do with them. i use the biggest ones as part of the tail on dahlburgs and poppers occasionaly, but what do you all use the smaller ones for???
thanks for any suggestions.
