FireStar is a shimmering blend of nylon fibres. Blend it in with your hand spun yarn or trap it among the fibres when you are needle felting. This fibre works well in wet-felting also.  The staple length is over four inches, so you could even hook it into a rug.

Fiesta is a blend of red and purple with a little bit of yellow.

FireStar is sold in a 30 gram package, (just over an ounce). 

A lot of impact for little cost.
