Notes before you start

• Source: "Edge for Sash Curtain", Richardson's Crochet Book No. 2 (Complete Crochet Book No. 2), Richardson Silk Company, Chicago and New York, 1915. Public domain in the USA.
• As printed — materials: Two Spools of Richardson's R. M. C. No. 20, White or Ecru; 16 1-inch Bone Rings. Gauge: Not given.
• Modernisation note: From Richardson's Crochet Book No. 2. That book prints only an abbreviation list (ch = chain stitch, s c = single crochet, d c = double crochet, t c = treble crochet, t t c = triple treble crochet, p = picot, la = lacet, gr = group, sp = space, cl = clover leaf) with no worked descriptions, so the stitches are read by the same key its companion Book No. 1 prints in full: s c = sc, d c = dc, t c = tr, t t c = trtr (triple treble). Book No. 2's heights therefore match modern US usage as well.
• Modernisation note: The book's abbreviations are written in modern US form: ch sts = ch, s c = sc, d c = dc, t c = tr, d t c = dtr, sl st = sl st, p = picot, sp(s) = space(s), gr = group (block), la = lacet, cl = clover leaf; “skip” = sk; “repeat *” = rep from *. Ordinal row names are written Row 1, Row 2, and so on.
• Modernisation note: Long printed paragraphs are split into one row, round or step per line; stitch order and counts unchanged. Section headings added for navigation.
• Modernisation note: Hooks are printed only as Richardson steel hook numbers, with no diameters, so no exact metric size can be read from the books. The metric sizes given are approximate starting points read across to the modern US steel-hook scale (in which a higher number is finer); work a swatch and change size to match any printed measurement.
• Modernisation note: No stitch gauge is printed for this design; work a swatch and match any printed measurement (given in the modern gauge line) before starting.
• Modernisation note: The threads are 1915 Richardson trade names with no exact modern equivalent, and the books print no yardage except where quoted in the materials. The modern equivalents given are approximations only: R. M. C. Cordonnet and Cordonnet Special (the book says it “matches the D. M. C. thread”, sizes 3 to 150) as mercerized cotton crochet thread of the same size number; R. M. C. Perle Cotton (Art. 15 and 15-B in hanks, Art. 35 in balls, sizes 3, 5, 8 and 12) as modern pearl cotton of the same size; Richardson's Crochet and Knitting Silk (“Perfect”, ½ oz on the ball; “Our Art”, ¼ oz) as a fine silk or silk-blend crochet thread about the weight of size 10–20 cotton; Richardson's Tatting Silk (100 yd on the ball) as a fine hard-twisted silk thread about the weight of size 20–30 cotton; Bed Spread Thread on cones as a heavy cotton crochet thread about size 3–5. Grecian floss (a silk embroidery floss) is used only for embroidery where it is named.
• Modernisation note: Check: the publication year. The book is catalogued as 1915 and is recorded here as 1915, but its own title page carries a 1916 copyright line and the deposit stamp on book page 2 reads April 1916.
• Modernisation note: No hook size is printed for this design, so the suggested hook is ours and is approximate.
• Modernisation note: Check: the point is printed as one paragraph with two starred repeats; it is read as covering each row of loops with single crochet, then making a new, shorter row of chain loops, until the point is reached.
• Modernisation note: Check: the colour is white or ecru, as named in the materials.
• Modernisation note: Metric conversions added.
