The fiber blends are not the same
Sandnes publishes Tynn Silk Mohair as 57% mohair, 28% silk and 15% wool. Knitting for Olive publishes Soft Silk Mohair as 70% mohair and 30% silk. The added wool in Tynn Silk Mohair is a material difference, while percentages alone cannot establish equal softness, halo, drape or finished fabric without physical testing.
One more ball can be necessary
Both yarns are sold in 25 g balls, but Tynn Silk Mohair contains approximately 212 m and Soft Silk Mohair 225 m. For an illustrative 900 m requirement, Soft Silk Mohair reaches the stated length with four balls, while Tynn Silk Mohair needs five whole balls. Recalculate from the pattern’s actual length and allow separately for swatching.
Do not transfer the label gauge
Sandnes publishes several possible stitch tensions from 18 to 24 stitches per 10 cm for Tynn Silk Mohair. The captured Knitting for Olive product page does not publish a gauge. A pattern that holds either yarn with a base yarn must be swatched with the complete strand combination; an individual label figure cannot predict the combined fabric.
Care and US retailer evidence differ
Sandnes recommends a separate wool-machine program for Tynn Silk Mohair followed by flat drying, while Knitting for Olive specifies cool hand washing and flat drying for Soft Silk Mohair. Mother Knitter and Heavenly Yarns provide the checked US retailer listings in these records. Confirm current color, dye lot, quantity and shipping details directly with the seller.
