B-TEX SURA Worsted is made from 100% combed 20-micron Patagonian merino wool and comes in 100 g / 3.53 oz skeins with approximately 166 m / 182 yd per skein. The fuller-bodied version of SURA combines softness, warmth and strong stitch presence, making it particularly suitable for garments where volume and texture are part of the design.
What should you know before choosing this yarn?
SURA is a Worsted / CYC #4 Medium yarn with approximately 166 m / 182 yd per 100 g / 3.53 oz. As a working reference, Budetex recommends 4.5–6 mm / US 7–10 knitting needles or a 4–6 mm / US G-6–J-10 crochet hook. Choose your color and calculate the number of skeins from your pattern yardage and gauge swatch.
Fiber and construction of SURA Worsted
SURA Worsted is made from combed 20-micron Patagonian merino wool. Its fine, flexible fiber is combined with a 3-ply construction that creates a substantial strand well suited to cables, ribbing and other textured stitches.
Micron count describes the diameter of the individual wool fibers, while Worsted describes the weight of the finished yarn. These are two different technical characteristics of the yarn.

How does it feel and behave?
The natural elasticity of merino wool allows the strand to give slightly as stitches are formed. In SURA Worsted, the fuller body of the yarn helps cables and textured stitches remain clearly visible while retaining the soft feel of fine merino wool.
Drape and firmness can be adjusted through gauge and needle or hook size. A denser gauge creates more structure, while a more open gauge allows greater movement in the fabric.
SURA Worsted has a 3-ply construction. Ply describes how the strand itself is built and should not be confused with its Worsted yarn-weight category.
What does merino wool bring to the finished fabric?
Softness against the skin
The fine 20-micron fiber contributes to a soft feel. Comfort against the skin also depends on individual sensitivity and the structure of the finished fabric.
Warmth and thermal comfort
Wool's natural crimp helps trap insulating air. In Worsted weight, SURA can create warm garments with substantial body.
Moisture management
Merino wool can absorb and release moisture vapor, contributing to comfort next to the body during wear.
Natural elasticity
The natural recovery of merino contributes to flexible cuffs, necklines and garments. Stitch pattern and care also influence the final shape of the fabric.
The final result will also depend on stitch pattern, gauge, garment construction and care.
What to make with SURA Worsted
- Sweaters and cardigans: for warm garments with visible stitch structure and substantial body.
- Cables and textured stitches: when you want the structure of the fabric to become a central part of the design.
- Hats, cowls and blankets: to make use of the warmth and body of merino wool in a Worsted-weight yarn.
BUDETEX RECOMMENDS
Choose SURA Worsted when you want the feel of fine merino wool in a fabric with more body, warmth and texture. For a lighter garment with less volume, compare it with SURA Fingering.

How much yarn do I need?
Each 100 g / 3.53 oz skein contains approximately 166 m / 182 yd. Divide the total length required by your pattern by the length per skein and round up. If you are working with several colors, calculate each color separately.
Actual yarn requirements vary with size, gauge, stitch pattern and any modifications to the design. Your pattern yardage and gauge swatch should always take priority over a general estimate.

SURA Worsted or another yarn?
Compare fiber content, construction, yardage and yarn weight before substituting one yarn for another. Even yarns made from the same fiber can produce very different fabrics when their yarn weights and constructions are different.
ANOTHER OPTION TO COMPARE
SURA Fingering keeps the same 20-micron Patagonian merino wool but uses a 4-ply construction and provides approximately 400 m / 437 yd per 100 g / 3.53 oz. It is a better reference for lighter, finer fabrics and requires adjustments to pattern, tools and gauge when compared with SURA Worsted.
