Our Yarn Bases
We have a large range of Yarn Bases that we use consistently at Third Vault Yarns.
All our wool bases are from non mulesed sheep and every base yarn we pick is one that we are happy working with ourselves for knitting, crochet or other fibre crafts.
Some of our bases are available in different put ups like 20g minis, 50g skeins, cakes or sock blanks.
Please note: needle and gauge are supplier suggestions and may not reflect the gauge you achieve based on your tension.
