Filet Insertion and Blue Picot Edge for a Towel No. 3173 (1916): vintage crochet pattern
A nine-row filet insertion in white worked on a chain-27 foundation of seven meshes, in which a chain-7 bar is thrown across the band and then caught back with single crochet over two rows to open a small figure in the centre, with a separate two-row blue picot edge worked into the linen below it.

Materials
- Size 30 mercerized cotton crochet thread in white — approximate; the book prints only its own trade name and size number
- A second ball of size 30 thread in blue for the edge — the book names the colour only by its own number, 3012, which it calls Blue
- Embroidery thread for the woven flower — the book names only “462 India”
- Steel crochet hook
- Tapestry needle for the ends
- A towel to set the insertion into
- Hook: No hook number is printed for this design — the materials line names two threads and stops. Start with a 1.25 mm (US steel 8) hook, which is ours, read across from the thread size, and change size until the insertion lies flat. Every other towel design on the same page prints “Crochet Hook, size 11”, but that has not been carried across here.

Notes before you start
- Source: "No. 3173 — Towel" (3173), Royal Society Crochet Lessons, Vol. 1, No. 7, H. E. Verran Company, Inc., New York, 1916. Public domain in the USA.
- As printed — materials: ROYAL SOCIETY White CORDICHET, size 30, 1 ball; Blue CORDICHET, No. 3012, size 30, 1 ball; 462 India for the embroidered flower; A towel to trim. Gauge: Not given.
- Modernisation note: Stitches are converted from the key this book prints itself, not from the date. The key is on book page 3, headed “CROCHET STITCHES”, facing a photographic plate of the same fifteen stitches on book page 2, and it defines every height in full. Single crochet is “insert needle in last chain and pull thread through, thus having two loops on needle. Wind thread once over needle and pull through the two loops” — the modern US single. Half double crochet is named and abbreviated separately, “wind thread once around needle, insert into chain and pull loop through. Wind thread around needle again and pull through three loops at once” — the modern US half double. Double crochet is “wind thread once around needle. Insert needle into chain and pull through; this leaves three loops on needle. Wind thread once around needle and pull through two. Wind thread again over needle and pull through two” — the modern US double, and because the book names the half double separately it cannot be the half double that Clark's 1923 book in another part of this library means by the same-looking abbreviation. Treble crochet is “made same way as Double Crochet, only at first wind thread twice over needle and pull thread through three times — two and two and two” — the modern US treble, written tr below; double treble takes three wraps and is written dtr. The key also defines the filet mesh as “chain two stitches, skip two stitches, one double crochet into next stitch” and a shell as “five double crochet in one stitch”. One trap in the printed abbreviation table on that page: it glosses “sp.” as spoke, not space, so no bare “sp.” anywhere in this book has been read as a space.
- Modernisation note: The book's wording is written in modern US form: “ch.” = ch; “s.c.” = sc; “h.d.c.” = hdc; “d.c.” = dc; “t.c.” and “tr.c.” = tr; “d.tr.c.” = dtr; “sl. st.” = sl st; “sk.” = sk; “p.” = picot; “m.” = mesh. Ordinal row names (“1st Row”, “2nd Row”) are written Row 1, Row 2; the book's “repeat from *” is written rep from *; and “finish off” is written fasten off. The book's own word “hole” for the gap it works into is kept, because that is the word it uses and it never abbreviates it.
- Modernisation note: The printed paragraphs are split into one row or step per line; stitch order and counts are unchanged. Section headings are the book's own where it prints them and ours where it does not. The OCR of this scan is rough — it prints “d.c.” variously as “dc”, “de” and “dic”, sets row labels as “lst Bow”, “Qnd Bow” and “8rd Row”, and drops words at the column breaks. Those quirks are kept in the excerpts and not in the rows.
- Modernisation note: The book names its threads by the maker's own trade name and colour number — Royal Society Cordichet in a stated size, sometimes with a colour number such as No. 3012. Those colour numbers were shade codes in the maker's own range and cannot be matched to any modern shade card, so they are recorded as printed and not converted. The stated thread size is read as roughly equal to the modern crochet cotton size of the same number — approximate only.
- Modernisation note: The book prints a hook number for most designs, but the number belongs to the maker's own scale rather than to any modern one, so it is recorded above as printed and the metric suggestion below is ours, read across from the thread size rather than from the page.
- Modernisation note: No gauge is printed for this design — the book prints no gauge, tension or stitch count per inch anywhere. Work a sample and change hook size until the piece lies flat.
- Modernisation note: Check: this is a towel trimming, so its length is set by the towel it trims; the book prints no length and leaves the number of repeats to the worker.
- Modernisation note: No finished measurement is printed for this design.
- Modernisation note: No yardage is printed for this design. The book gives ball counts only, and where it does they are recorded above as printed; no length in yards or metres appears anywhere in the book.
- Modernisation note: Check: the foundation count squares with the book's own general filet directions on book page 45 — “for the foundation ch. make 3 times as many chains as meshes shown in first row of diagram and add 1. Always ch. 4 to turn”, with the first mesh worked into the 9th chain. Seven meshes give 22 chains, and the 5 more chains this design starts with make the 27 it prints. Nothing has been reconstructed; the arithmetic is noted only because the OCR of the count is faint.
- Modernisation note: Check: this design is filet but it is not chart-dependent. Every row is printed in full, the figure in the centre is made by the chain-7 bar and the single crochet caught back over it in Rows 6, 7 and 8, and no squared diagram is printed for it anywhere in the book.
- Modernisation note: Check: the picots in the blue edge are the one place in this file where the book prints a chain count for a picot — “ch. 4, form p.” — and that count is kept above.
- Modernisation note: Check: the OCR of Row 6 is broken across the printed column, stranding the fragment “. 2, 1 dic, ch. 5, 1 s.c. around ch. 7, ch. 5, sk. 1” below the row it belongs to. The page image reads the row as it is written above.
- Modernisation note: Check: “462 India” is the book's whole naming of the embroidery thread; no brand, no weight and no colour word is printed with it, so nothing has been supplied.
- Modernisation note: Check: every tall stitch in this design is the book's d.c., the modern US double crochet by the printed key. No treble appears in it.
- Modernisation note: The line about where the insertion and edge go on the towel is ours, read from the photograph on book page 40; the book prints the two pieces separately and does not say.

Frequently asked questions
Where is the No. 3173 — Towel pattern from?
It was published as "No. 3173 — Towel" in Royal Society Crochet Lessons, Vol. 1, No. 7 by H. E. Verran Company, Inc., New York in 1916. The publication is in the public domain in the United States; this version is transcribed and modernised by crochetpatterns.io.
What yarn or thread do I need for the No. 3173 — Towel?
Size 30 crochet cotton (approximate). Not printed — the book gives only a ball count.
What hook should I use?
No hook number is printed for this design — the materials line names two threads and stops. Start with a 1.25 mm (US steel 8) hook, which is ours, read across from the thread size, and change size until the insertion lies flat. Every other towel design on the same page prints “Crochet Hook, size 11”, but that has not been carried across here. Gauge: No gauge printed.
