A Sentro knits a plain stockinette tube at one fixed circumference — 22, 40 or 48 stitches around, depending on your machine. It has no needle selection, so it cannot shape a garment or carry two colours in one row. What it can give you is a precise tube: a stitch count you already know, and a row count you choose. Writing that down accurately is the whole job, and it is what this tool does.
Stripe designer. List your colours in knitting order with the rows each one gets, set a total, and the sequence repeats until it fills the tube — the last block is truncated so the total is exact. You get a row-by-row card (“Rows 1–6: knit Blush. Rows 7–10: knit Teal — then change yarn”) plus a count of yarn changes, so you know how many ends you will weave in before you start.
Photo to chart. A picture is reduced to 2–4 colours on a grid exactly as wide as your machine’s needle count, needle numbers along the top. A Sentro feeds one yarn at a time, so treat this as a duplicate-stitch map for after the tube is off the machine.
Row counter. Finished length × your measured row gauge = rows. A fold-over beanie is a doubled tube, so it takes twice that.
Needle count sets the circumference; row gauge sets everything else. Knit 20 rows in your yarn, measure the length of the tube, and divide 20 by the inches you got. Then rows = finished length in inches × rows per inch, doubled for a fold-over hat, plus 2–4 waste rows for gathering the crown.
48-needle Sentro, worsted (#4) yarn, a measured gauge of 30 rows per 10 cm. That is 30 ÷ 3.937 = 7.6 rows per inch. An adult fold-over beanie finishing 8.5 in tall:
At the 7.0 rows/inch default the same hat is 120 rows — which is exactly why the swatch matters: half a row per inch is ten rows of hat. Now put four-row stripes in two colours across those 130 rows and the generator writes 33 blocks, 32 yarn changes, 68 rows of colour A and 62 of colour B, and prints the whole schedule on one page you can prop next to the machine.
No shaping. No decreases, no armholes, no crown. Every Sentro project comes off as a tube you finish by hand — gather the top with a yarn needle, seam a flat end, or crochet a brim on. To turn a tube into something shaped, the machine shaping calculator works out where to gather and seam; the hat size calculator tells you what circumference to aim for before you cast on; and the Sentro needle chart lists what each needle count actually makes.
Tubes and flat panels: beanies, cowls, scarves, leg warmers, sleeves, bag bodies, and long strips you seam into a blanket. The machine knits plain stockinette at one fixed circumference, so everything starts as a tube or a rectangle and gets its shape afterwards from folding, gathering and seaming by hand.
For a fold-over adult beanie on a 48-needle Sentro in worsted (#4) yarn at about 7 rows per inch, knit roughly 120 rows: 60 rows for each layer of the doubled tube, plus 2 to 4 waste rows for gathering the crown. A single-layer slouchy at 11 inches is about 77 rows. Measure your own 20-row gauge swatch first, because tension changes this number more than anything else does.
Yes. This generator is free with no signup, and it writes your pattern rather than handing you someone else’s: a printable row-by-row card with the stripe sequence, every colour change, the cast-on and the finishing notes. Nothing is uploaded; the whole tool runs in your browser.
No. A Sentro feeds one yarn at a time, so multi-colour knitting is done with stripes, by changing yarn between rows, or by adding a design afterwards in duplicate stitch. The stripe designer writes the row-by-row colour changes; the photo mode makes a needle-accurate chart you can follow in duplicate stitch.
No. A Sentro has no needle-by-needle selection, so it cannot increase, decrease or shape a garment while it knits. It gives you a tube of one fixed circumference and a row count. Shaping happens off the machine: use the machine shaping calculator to work out where to seam, gather and cut a tube into a shaped piece, and the hat size calculator to check the finished circumference before you start.
