Free filet crochet pattern

Brain Cog

By StitchingLab ·

This 60×60 chart finishes at roughly 15×15 inches in size-10 thread filet mesh, using 2 colors — a clean two-color project — a good first counted chart. As filet crochet the solid blocks sit on open mesh — curtain panels and table runners are the classic use. The grid, materials estimate, and written row-by-row instructions below are all free; open the chart in the editor to resize it or swap the palette to yarns you already own.

Project kit

Gear this chart actually calls for

  • Clover Amour Crochet Hook Set

    Comfort-grip hooks in every size a chart can call for — one set covers the whole CYC weight range. — 5.5-6.5 mm (I-9 to K-10½)

    Buy on Amazon →
  • Tapestry Needles

    Blunt-tip needles for weaving in the ends every color change leaves behind.

    Buy on Amazon →
  • Locking Stitch Markers

    Mark pattern repeats, color-section starts, and the first stitch of the round so a miscount never survives a row.

    Buy on Amazon →
  • Yarn Ball Winder

    Center-pull cakes feed evenly and stand still while you work — worth it once a project runs to many skeins. — 7 skeins wind into tidy center-pull cakes

    Buy on Amazon →
  • Sharp Yarn Snips

    Small, sharp snips cut yarn clean at every color change — cleaner joins and easier weaving-in than scissors.

  • Up to 11 strands will be active in a single row — wind one bobbin per strand before you start to avoid tangles.

Written instructions

  • spOpen mesh
  • blBlock

Before you start

  • Open mesh (sp) = dc, ch 2, skip 2; block (bl) = 3 dc plus the shared boundary dc — a row of n cells always totals 3n + 1 dc.
  • Foundation: ch 3x(cells) + 3 if Row 1 starts with a block (turning ch-3 counts as first dc), or + 5 if it starts with a space (first dc in 8th ch from hook).
  • Turn with ch 3 (counts as dc) before a block, ch 5 (counts as dc + ch 2) before a space.
