Long Filet Sweater with Long Sleeves and Morning Glories (1921): vintage crochet pattern

Materials

• Lustrous mercerized cotton about as heavy as size 5 pearl cotton or size 3 crochet thread — approximate only; the original “Silk Finish” Crochet Cotton has no printed size, so match the gauge
• Steel crochet hook (original: No. 2)
• Tapestry needle
• Hook: Start with 2.2 mm (steel hook US steel No. 2) — approximate conversion of the printed No. 2 hook; change size to match the printed meshes to the inch.

Notes before you start

• Source: "Long Sweater with Long Sleeves", J. & P. Coats Crochet Book No. 7: Sweaters, Yokes, and Boudoir Caps (designed by Anne Orr), J. & P. Coats, Pawtucket, R.I., 1921. Public domain in the USA.
• As printed — materials: Coats "Silk Finish" Crochet Cotton; No. 2 Hook. Gauge: 4 meshes to the inch.
• Modernisation note: Stitches converted by the book's own stitch key (“Abbreviation Stitches and How to Make Them”), not by name. Its slip stitch (sl st) = sl st. Its single stitch (s st: “insert the needle in the stitch directed, draw the working thread through this stitch, making two on the needle, then draw the working thread through these two loops”) = modern US sc. Its treble crochet (tr: thread around the needle once, draw through, then through two loops twice; “three chains equal one treble”) = modern US dc. Its double treble (dtr: thread around twice, loops worked off two at a time three times) = modern US tr. Its triple treble (tr tr: thread around three times) = modern US dtr. So every “s st” is written sc, every “tr” dc, and every “d tr” tr.
• Modernisation note: Filet crochet as the book defines it: a space (sp) is 1 dc, ch 2, sk 2 sts, 1 dc (“For a space at the beginning of a row, chain five, which allows three for the treble on the edge, and two for the usual chain”); a block (bl, written “block” here) is dc worked in consecutive sts — “there are four trebles in the first block and three trebles in each following block”, so a row of blocks has 3 dc per block plus 1. Ch 3 at the beginning of a row counts as the first dc.
• Modernisation note: The book's “New Method of Adding Meshes at Last End of Row” (book page 4), for rows where the directions or chart add meshes at the end of a row: instead of making the last dc of the block already there, ch 2 and sl st into the loop where that last dc would go; then ch long enough for the extra meshes (ch 6 for 1 mesh, ch 9 for 2, ch 12 for 3, adding 3 ch for each further mesh); turn and work spaces or blocks along the ch as the chart shows; sl st to the top of the last mesh before the added ch; turn, sl st to the end of the added meshes, and you are ready to start the next row. Adding meshes at the beginning of a row is done the usual way, by working extra blocks or spaces on a ch made at the end of the preceding row.
• Modernisation note: Period wording modernised: s st, tr, d tr written as sc, dc, tr (see the stitch note); “bl” written as block; “sp” kept as sp (filet space); “p” written as picot; “needle” (the crochet hook) as hook; “throw cotton over” as yo; “skip” as sk; “fasten”/“fasten cotton” as join thread; “break cotton” as fasten off; “repeat” as rep; “drop off”/“leave off” meshes kept as printed (stop working over those meshes); ordinal row names (“1st Row”) written as Row 1, and “Row” is kept even where a piece is worked round (as the book does).
• Modernisation note: Picot as the book defines it: “usually made by a chain of three or five, then a slip stitch in the first chain.” The size is not given in the individual designs, so use ch 3 (or ch 5 for a larger picot), sl st in the first ch.
• Modernisation note: The filet charts (the book's “working patterns” or “design”) are printed as pictures and are not transcribed square by square here; rows that say “follow design” are kept as printed, and the chart page is listed with this pattern's images. Each chart square is one mesh: a filled square is a block, an open square is a space.
• Modernisation note: Long printed paragraphs are split into one row or step per line; stitch order and counts unchanged. Section headings added for navigation.
• Modernisation note: Hooks are 1921 steel crochet hook numbers; the book prints no diameters. The metric sizes given use the modern US steel-hook scale (No. 2 ≈ 2.2 mm, No. 7 ≈ 1.65 mm, No. 8 ≈ 1.5 mm, No. 10 ≈ 1.3 mm, No. 12 ≈ 1.0 mm, No. 13 ≈ 0.85 mm, No. 14 ≈ 0.75 mm) and are approximate only — period numbering may differ, so match the printed meshes to the inch instead. The book's own table pairs, for example, size 5 thread with a No. 2 hook for 3 meshes to the inch, size 70 thread with a No. 12 hook for 8 meshes, and size 100 thread with a No. 14 hook for 9½–10 meshes, and warns that “if the thread is loosely held, the meshes will increase to the inch”.
• Modernisation note: Threads are 1921 J. & P. Coats products with no exact modern equivalent. Approximate modern equivalents: Coats Mercerized Crochet No. 30–100 as mercerized cotton crochet thread of the same size number; Coats Pearl Cotton No. 5 as size 5 pearl (perle) cotton. The book prints no yardage or ball counts, so no yardage is given.
• Modernisation note: “Meshes to the inch” is the book's gauge: count filet meshes (spaces or blocks) across 1 in (2.5 cm) of work.
• Modernisation note: Sizes are rarely printed; vintage fit and ease differ from today's. Widths marked “calculated” are ours, from the printed mesh count and meshes to the inch — compare them with a garment that fits before starting.
• Modernisation note: The chart page (book page 15) shows the back of the sweater with the morning glory hem, and patterns for the cuff and the collar (front and neck band).
• Modernisation note: Check: “When the sleeve is 45 meshes wide” — the sleeve is 54 meshes long; “wide” is read as the depth of the sleeve worked since the neck division. Follow the chart.
• Modernisation note: Check: “a p between every 3rd and 9th bl” is kept as printed; it probably means picots spaced alternately 3 and 9 blocks apart, or at every 3rd block. Compare with the photograph.
• Modernisation note: Check: the sash fringe length and the keepers' use (one row of 10 blocks, sewn to form a loop at each underarm seam) are not described further.
• Modernisation note: Check: the book gives no size for Coats “Silk Finish” Crochet Cotton; the modern thread suggestion is ours, chosen for 4 meshes to the inch with a No. 2 hook.
• Modernisation note: The sleeve directions are split into steps; counts unchanged.
• Modernisation note: Finishing line added.
• Modernisation note: Metric conversions added.
