Thread Guide
Gathering threads (for the pleater) and smocking threads (for the stitches) are different jobs. Choose each for strength or beauty — not both from one spool.
Floche
Soft, loosely twisted cotton with a gentle sheen. The classic English smocking thread. Covers mountains smoothly without harsh cordiness.
- Sizes: Typically used as-is (not stranded like mouliné).
- Color notes: DMC and specialty ranges; soft pastels dominate heirloom work.
- Best for: Cables, waves, and heirloom bishops on batiste
Perle / Pearl Cotton
Non-divisible twisted cotton. Holds a round cord profile — excellent for crisp cables and waves.
- Sizes: #3 (heavy), #5, #8 (most common for smocking), #12 (fine detail).
- Color notes: Full DMC perle ranges; #8 in dusty blue, rose, sage for vintage palettes.
- Best for: Crisp structural rows; #12 for fine trellis
Stranded Cotton (Mouliné)
Divisible six-strand. Use 2–3 strands for most smocking; more for bold work. Slightly flatter than perle.
- Sizes: Strand count is your ‘size’ control.
- Color notes: Widest color range — ideal for matching Liberty prints.
- Best for: Color-matched motifs and blended fields
Silk embroidery thread
Luminous on batiste and silk grounds. More delicate; shorter lengths recommended.
- Sizes: Follow manufacturer weight; test tension on scraps.
- Color notes: Soft ivories, blush, gold for christening work.
- Best for: Christening and special-occasion accents
Choosing weight to match the stitch
Thread weight is really a coverage decision: it sets how much of each mountain the stitch hides and how proud the cord sits. Too heavy and structural rows look clumsy on fine batiste; too light and they disappear.
- Cable & outline (structural): want a defined cord — perle #8 or floche read crisply.
- Trellis & fine diamonds: want delicacy — perle #12 or 2 strands so the lattice does not overwhelm the ground.
- Honeycomb: a slightly softer thread (floche or 2–3 strands) lets cells open without stiffening the elastic.
Stranded cotton in practice
With mouliné, strand count is your dial. Always separate and recombine strands — pull each strand out singly, then lay them back together — so they sit flat and parallel instead of twisting into an uneven cord. Two strands is the common smocking default; drop to one for the finest lawn, rise to three or four for folk-weight boldness.
Handling & length
- Keep lengths short: ~18 inches. Longer thread abrades against the fabric on every pass and starts to fuzz — worst with floche and silk.
- Mind the twist: let the needle dangle periodically to unwind accumulated twist, which otherwise kinks and knots.
- Colorfastness: test any strong color on a damp scrap before committing it to a christening piece that may be washed.
Quick recommendations
- Learning cable on batiste → floche or perle #8
- Fine trellis on lawn → perle #12 or 2 strands mouliné
- Bold folk smocking → perle #5
- Pleater gathering → strong cotton/poly; remove after smocking unless the pattern says otherwise — see threading
