Do you use scented soap on Amber Waves of Fiber product? 
No. The yarn is washed in an unscented wool wash after dyeing. 

Is alternating skeins necessary for a consistent finished product? 
Yes. Due to the nature of hand-dyeing, there can be great variation among skeins- even skeins from the same dye lot. When working with small batch, hand-dyed yarn, it is important to alternate skeins for a consistent look in your finished product if you are using more than one skein. Otherwise, you may end up with unwanted color pooling or a visible line when starting a new skein.
