Use Lime for cross-bred and coarse wools, such as Romney, Leicester or Lincoln, and fibres of similar or coarser diameter, such as Mohair, human hair and Hemp and Linen.
Lime is a thick needle and should not be used with medium and finer fibres, (such as Merino or Alpaca)

Pick Lime

• to secure fibre designs on thicker batts with a vertical stabbing action and to cross-link layers of wool in a pile prior to wet felting.

• to define design outlines prior to wet felting using an angled stabbing action.

• for speedy initial felting during early stage felting of sculptural projects, use both stabbing and jiggling actions. 

Once fibres begin to form felt this needle resists penetration and becomes harder to use, so change to needles such as Pink or Mauve to form felt farther or Brown to create indentations.

Green
Needle description: 36 gauge / 3x3x3 barbs / 3 inch /  fast;             

Use Green for early stages of felting coarse (cross-bred) wools. Green can also be used with medium wools such as Corriedale and Halfbred where the presence of pronounced puncture marks is not an issue.
Green has close barb spacing for fast action.

Pick Green

• for quick securing of unfelted fibres in thinner batts and 3-D projects.

• for quickly forming deep depressions in softly felted balls. 

• to quickly draw fibre right through flat felt and leave a “hairy” texture on the underside. 

• for rooting hair on a plastic (vinyl) doll's head, also Blue

Green has high penetration resistance and becomes difficult to use as felt becomes firmer, so change to needles such as Pink or Red
