Baby makes
How much wool to knit a baby cardigan?
Two current DROPS designs allocate 350 m for a 0–1 or 1–3 month knitted cardigan: two 50 g balls of Baby Merino. Both allocate 525 m for their 6–9 month size. A third, six-colour design shows why a colourful cardigan can need far more whole balls than a plain one.

How many balls of wool by baby size?
These are pattern-by-pattern purchase quantities, not an average for all cardigans. “0–1 months” and “1–3 months” are the designers’ labels. Their child-height ranges are not finished garment lengths. The Stroll cardigan also states its shoulder-to-hem length.
The three fine-yarn choices below share a listed 24-stitch knitting tension, but their fibre and care differ. DROPS describes Baby Merino and Safran as sport/5 ply, and Flora as 4 ply. A shared yarn group is a starting point; make the pattern’s tension square.
| Design | Age label | Child height (cm) | Finished length (cm) | Original length | Baby Merino (175 m) | Flora (210 m) | Safran (160 m) |
|---|---|---|---|---|---|---|---|
| Stroll in the Park, cardigan only | premature | 40–44 | 20 | 350 m | 2 | 2 | 3 |
| Stroll in the Park, cardigan only | 0–1 months | 48–52 | 24 | 350 m | 2 | 2 | 3 |
| Stroll in the Park, cardigan only | 1–3 months | 56–62 | 28 | 350 m | 2 | 2 | 3 |
| Stroll in the Park, cardigan only | 6–9 months | 68–74 | 30 | 525 m | 3 | 3 | 4 |
| Stroll in the Park, cardigan only | 12–18 months | 80–86 | 33 | 525 m | 3 | 3 | 4 |
| Stroll in the Park, cardigan only | 2 years | 92 | 36 | 525 m | 3 | 3 | 4 |

Three yarns: wool, wool blend and cotton
Baby Merino is the original 100% wool yarn, 175 m per 50 g. Flora is 65% wool and 35% alpaca, 210 m per 50 g, hand wash only. Safran is 100% cotton, 160 m per 50 g. The ball counts compare lengths, not identical fabric.
For a gift, check how the recipient wants to wash it. Cotton changes elasticity and drape; Flora changes the care routine. Choose a pattern written for the fibre where possible, rather than assuming matching tension makes every substitution suitable.
Why a six-colour cardigan needs more balls
DROPS Baby 5-8 allocates 100 g in the main shade and 50 g in each of five contrast shades for 0–3 months: seven 50 g balls bought, or 350 g in total. That is 1,225 m of purchased Baby Merino across six colours, not a measured claim that every metre is used.
A mixed pack is useful only if its shade quantities cover that list. It cannot replace two same-colour balls simply because its total weight is bigger.
Measure before choosing an age label
Use the child’s height and the source schematic, then check chest, shoulder-to-hem and underarm-to-cuff measurements. Finished chest includes the pattern’s intended ease. Longer sleeves, wider bands and a longer body alter the quantity.
Stroll in the Park also includes shorts. Our cardigan table excludes the shorts and the larger “entire set” material list. Otherwise you would be buying yarn for two garments by mistake.
The method and its limits
This page uses three published knitting designs from one manufacturer, checked on 12 October 2026. Two current one-colour designs supply the size table; the older colourwork design is a separate buying example. We have not knitted or weighed them.
Convert each original ball allocation to metres, divide by the substitute’s actual ball length, then round up each colour. These are shopping allowances. They are separate from our crochet baby-cardigan figures; neither technique always uses more yarn across every stitch and fit.
Tension, care and the shopping list
The two current designs use 2.5 mm and 3 mm needles and 24 stitches × 32 rows per 10 cm in stocking stitch. Use the needles that give your own square the required size. A ball-band tension is not permission to skip the pattern’s check.
Keep the bands with the gift. Baby Merino allows a gentle 40°C machine wash with no fabric softener and flat drying; Flora asks for hand washing at up to 30°C; Safran allows gentle 40°C machine washing and flat drying. Check the actual band and any trim too.
Check before you move on
- Choose the pattern by measurements, not age alone
- Use the cardigan-only materials list
- Match both stitches and rows per 10 cm
- Round each colour separately
- Check care and button requirements in the original pattern
