1/14NM & 1/11.5NM lacewt soft spun & boucle
The boucle yarns from Lineapiu of Italy are a single polyamide filament with a cashmere fibre wrap. This makes for soft but strong laceweight, mostly cashmere by weight, with the great crinkly effect. It also gives a balanced yarn - the filament has no residual twist so there should be no bias with the boucle yarns even though they are singles.
The 1/14s and 1/11.5s non boucle singles from Todd & Duncan are soft spun and steam set to give lower twistiness, but knitters should be aware that as unbalanced singles yarns they do still retain some residual bias. They have great colours though, and work well for weavers too..
