Design repeat motifs and tile them in one piece around your tube — works with Sentro, Addi Express, Jamit and any circular machine from 10 to 100 needles. Free, no signup.
A cranked circular machine — Sentro, Addi Express, Jamit — knits a closed tube of a fixed number of stitches. That single fact drives everything here. Draw a motif on the grid, and the tool tiles it around the tube, checks whether it joins in one piece, sequences your colour bands, and writes the whole thing out as numbered rows you can print and prop next to the machine.
The repeat check. A motif only closes without a visible seam when its stitch width divides the needle count exactly. 48 needles ÷ an 8-stitch motif = 6 perfect repeats. 46 needles ÷ 8 = 5 repeats with 6 stitches left over, which the tool knits in the background colour and flags, listing the widths that would fit instead.
The band sequence. Real machine projects are not one motif forever — they are a plain brim, a band of pattern, more plain, and so on. Stack plain stripes and motif repeats in the order you will knit them and the tool numbers every row from cast-on to cast-off.
48-needle Sentro, an 8 × 8 heart motif, and a band sequence of 10 plain rows, the motif twice, then 10 plain rows:
Change the machine to a 46-needle Addi Kingsize and the same motif gives 5 repeats with 6 stitches over. Those 6 needles knit in the background, and the tool tells you the only motif width between 2 and 16 that divides 46 cleanly is 2 stitches — which is honest, and worth knowing before you knit 36 rows of nearly-matching hearts.
No two-colour rows, and no shaping. A cranked machine carries one yarn, so contrast stitches are hand-fed on the marked needles or added later in duplicate stitch — the per-needle chart works for both. And because there is no needle selection, the tube comes off one size the whole way down. To turn that tube into a shaped piece, use the machine shaping calculator; to check a finished hat circumference before you start, use the hat size calculator. Everything in the cluster is listed on the machine knitting hub.
Yes. Set the needle count to match your machine — Addi Express Kingsize 46, Addi Express Professional 22, Sentro 22, 40 or 48, Jamit 48 — and the motif tiles around your exact tube. Any count from 10 to 100 needles works.
Because the tube is a closed loop, a motif only joins in one piece when its width divides the needle count evenly. The tool shows the repeat maths, for example 48 needles divided by an 8-stitch motif gives 6 perfect repeats, and warns you when there is a remainder, suggesting motif widths that fit your machine.
Not on their own. A cranked machine carries one yarn at a time. Knitters work charted motifs by hand-feeding the contrast colour on the marked needles, or knit the tube plain and add the design afterwards in duplicate stitch. This tool gives you the per-needle chart and the row-by-row runs either way.
Anything that starts as a tube or a flat rectangle: beanies, cowls, scarves, leg warmers, sleeves, bag bodies and seamed blanket strips. The machine cannot shape, so every project is finished by hand — gathered at the crown, seamed flat, or given a crocheted brim.
