JaggerSpun Maine Line 3/8 Yarn description:

Jaggerspun’s versatile, high quality 27.5 micron worsted spun "sport gauge" wool yarn is a staple for commercial and recreational knitters and weavers. It is a perfect pattern weft in weaving.

Made in Maine of soft, medium grade wool, these yarns will easily make a way into clothing and fine home decor projects. As worsted spun yarns, they are smoother and shinier than woolen spun yarns so won't full as much when washed and finished, so plan on a closer sett or tighter gauge than you would plan for woolen spins (make a sample swatch to determine if you like the finished fabric).

JaggerSpun yarns are dyed with the finest dyes possible. Excess dyes may be present in some colors so sample first. If excess dye is present, skein the yarn and rinse until the water runs clear. Deep purples may not be colorfast when exposed to sun, so avoid prolonged exposure to bright light.
