Re: Flashabou
A few thoughts,
You can buy wide plastic ribbon from a craft store and cut it many times lengthwise thus creating your own to your own design requirements while being inexpensive. I am using flashabou/mylar by itself or as an accent piece amongst similar colored bucktail and it works very well.
I have found at a local dollar store gold, silver, blue and purple children's wigs and some decorations (ie birthdays) for kids that were made in China which appear to be made of mylar/tinsel that can be readily converted for use. Each wig is going to give me a supply for two or three winters of lurebuilding. The material appears to be quite durable, especially the stuff found in decorations. Just tested it out last weekend at the lake.
Hope this helps
