was wondering if anyone knew what patterns i can tie with this material, which i don't know what the material is. this material was given to me and i have no idea what it is. i was given 4 bags, and on the bags it says THE SPECTRUM by The Andra Co. they are numbered, # 1 is a dark grey,# 2 is a light green, # 9 is a tan color, and # 11 which is a very dark brown. i assume these are the bags that the material came in. so does anybody know what the material is,and used for? and any patterns with the material?

Thanks
