In modern Scandinavian knit design, “held together” (knitting with two or more strands at the same time) has become an extremely popular technique. Designers like PetiteKnit use it across a wide range of their best-known patterns, and there are several good technical reasons for that.
By combining multiple strands you can hit a specific weight category that does not exist as a single yarn, blend colours to create a unique play, pair a smooth plied yarn with a carry-along strand for a soft fibre halo, or use up smaller leftovers from your stash.
The technique is straightforward, but there are a few things worth knowing.
What two strands equal in weight
When you hold two strands together, they structurally behave as one thicker strand. Below is the standard conversion table based on Craft Yarn Council weight categories:
| Strand combination | Resulting category |
|---|---|
| 2 × Lace | Fingering |
| 2 × Fingering | DK / Worsted |
| 2 × Sport | Worsted |
| 2 × DK | Bulky |
| 2 × Worsted | Super Bulky |
| 2 × Bulky | Super Bulky / Jumbo |
Many producers use their own classification systems. Major Nordic brands such as DROPS use a letter-based group system, where the conversion looks like this:
| DROPS combination | Resulting yarn group |
|---|---|
| 2 × Group A (Lace-Sport) | Group C (Worsted) |
| 3 × Group A | Group D (Bulky) |
| 4 × Group A | Group E (Super Bulky) |
| 2 × Group B (DK) | Group D (Bulky) |
| 2 × Group C (Worsted) | Group E (Super Bulky) |
These tables are guides. CYC, DROPS and WPI do not measure exactly the same thing, so categories can overlap. Gauge and a swatch should always determine the final choice. A more detailed overview can be found in the Guide to yarn weights.
Combinations that work
Silk mohair paired with a smooth strand
This is the definitive classic in modern knitting. Silk mohair or brushed alpaca weighs very little and typically sits in the very fine lace category. When held together with a solid fingering or DK strand, it lays a dense, luxurious fibre halo across the fabric. This is the technique that defines the look of popular designs such as The September Sweater.
The combination has three clear advantages:
- The loose mohair fibres act as a visual “glue” that binds the stitches together.
- The fabric becomes airy and light without losing its structural shape.
- The colours blend together, making it easy to mask minor shade differences if you are using leftover yarn.
Two strands of fingering (becomes DK)
If you have two smaller leftover skeins in fingering weight, you can easily combine them and knit a pattern designed for DK yarn. This is an excellent, stable solution for smaller projects like hats, cowls and mittens.
Three strands of lace (can approach DK)
Three strands of lace can in some cases approach DK, but it depends heavily on yardage and fibre. It gives you the opportunity to experiment with blending colour transitions, but always knit a gauge swatch first.
Two contrasting colours (marled effect)
Even if you are using two yarns with identical fibre content and weight, you can create a striking visual effect by choosing two different colours. The result is a lively, marled texture with fine colour shifts across the stitches.
What to watch out for
Yarn construction and twist
The yarn’s structure has a significant impact on how the two strands sit together on the needle. Multi-ply yarns with several visible strands naturally twist and nestle harmoniously around each other. If you combine two singles yarns (single ply), however, the fabric can in some cases begin to twist, because they lack the internal balance provided by opposing twist.
Fibre balance and elasticity
When you blend two different fibre types, you lock their properties together:
- Wool + Alpaca: You get wool’s excellent spring combined with alpaca’s heavy, elegant drape. Be aware, though, that heavy fibres like alpaca can cause the finished garment to stretch lengthwise over time if the wool content is too low.
- Wool + Cotton: Here you lose a significant portion of wool’s natural elasticity. Cotton does not spring back, which means elastic elements like rib cuffs will quickly lose their shape and go slack.
Needle adjustment and gauge swatch
Even though the table says that two strands of fingering becomes DK, it is always a good idea to knit a gauge swatch first. If you have a tight tension, the combined strand may end up behaving more like a thinner Sport weight.
Three classic combinations that often work well
If you want to experiment with the technique, these three pairings are well known and frequently used in Scandinavian knitting:
- Sandnes Sunday + Onling Tynn Silk Mohair: Gives an unmatched, soft and stable sweater structure.
- Filcolana Arwetta + Filcolana Tilia: The classic, durable Danish combination, available in a wealth of colourways.
- Knitting for Olive Merino + Knitting for Olive Soft Silk Mohair: Two qualities from the same producer, spun specifically to complement each other.
How Nysta handles multiple strands
Matching multiple strands requires a different calculation model than substituting a single yarn. In Nysta, we have developed a pairing algorithm for held-together patterns.
Nysta evaluates whether two yarns are likely to work well together in the same project, based on thickness, fibre, elasticity and construction.
We analyse the fibre balance and construction of the combined strand and flag a warning if two yarns risk working against each other (e.g. loss of elasticity).
Frequently asked questions
What does held together mean in knitting? Held together means that you knit with two or more strands held on the needle at the same time. The strands function as one combined yarn, and the resulting thickness roughly equals the sum of the individual strands’ weight categories.
Can you knit with two different yarns at the same time? Yes, that is the whole point of the technique. The most common combination is a smooth base yarn in fingering or DK held together with a fine silk mohair as a carry-along strand. Be aware that different fibre types can affect elasticity and drape.
Which yarns work well together as held together? A solid fingering or DK strand combined with silk mohair is the classic and most stable combination. Two strands of fingering give a good DK weight. Avoid combining two singles yarns, as they can cause the fabric to bias.
Can Nysta find held-together combinations in my stash? Yes. Nysta calculates combinations from your leftover yarns and evaluates how they will work as a pair. If two yarns risk working against each other, the app flags a warning.
