Solid heart: Filet Crochet Chart Generator

This heart uses filled mesh cells as a silhouette inside an open frame. The design goal is a small insert for a larger panel, with a central notch, two balanced shoulders and a single-cell point. A visible empty margin keeps the silhouette away from the edges. The design has algorithmic count checks only; neither a finished size nor physical yarn testing is claimed.

Build the binary picture

In the Filet Crochet Chart Generator, choose nine mesh columns and nine rows, US terminology, and ivory #F4F0E8 for open cells with blue #243BCE for solid cells. Use one actual yarn color: the blue represents density, not a blue yarn strand. Read this record from the top of the picture downward: 000000000, 001101100, 011111110, 011111110, 001111100, 000111000, 000010000, 000000000, 000000000. The tool's first worked row is at the bottom, so enter these rows in reverse order when preparing JSON. In the editor, start from the bottom two empty rows and build upward.

Prepare an appropriate fabric

Choose a smooth yarn whose loops remain visible against your working surface. A stable cotton is a useful trial option, but consult its care instructions. Start with a matching hook and make the open-mesh exercise first. Keep nine column positions marked on paper so an edited cell cannot silently shift the motif sideways. You also need scissors, a tapestry needle and removable edge markers. Final dimensions and yarn consumption require your own washed sample.

Read the graph and check symmetry

The center column is column five. Compare columns one and nine, two and eight, three and seven, then four and six on every picture row. Each pair agrees, so the image is horizontally symmetric. The isolated point sits on column five. In contrast, the top shoulder row has an open center cell between two two-cell lobes; filling that cell removes the notch and changes the intended design.

Reconcile cells with stitches

Nine mesh columns require twenty-eight stitch positions in each row and thirty-one chains at the start, including the starting boundary chain. There are twenty-seven solid cells among eighty-one total cells. An open cell adds one post and two chains after the shared first boundary; a solid cell adds three posts. Across the nine rows, ninety baseline posts plus fifty-four extra solid-cell posts give 144 counted post positions. Nine boundary positions are supplied by counted starting or turning chains, leaving 135 worked double crochets. The remaining fifty-four open cells provide 108 mesh chains. Their combined 252 positions equal nine times twenty-eight.

Correct a misplaced section

If the point appears at the top, the row list was entered in picture order instead of working order. Reverse the row order, not each row's columns. If one shoulder is wider, compare mirrored cell pairs before undoing the crochet. If your fabric has an additional post at every cell, revisit shared boundaries; the silhouette can look plausible while the panel becomes much too wide.

Apply and save the study

Use the motif as a planning insert for a cushion or a decorative panel after measuring gauge and designing the surrounding fabric. Export JSON after checking the binary rows, and export SVG for a printed density map. Consult reading stitch charts before converting mesh cells into unfamiliar symbols.

FAQ

Should every blue cell use different yarn? No, this is monochrome filet. Is the outer frame an added border? No, it is part of the nine-by-nine mesh. Can I enlarge the heart by using a larger hook? That changes gauge and drape; redesign the cell dimensions if you need more picture detail.
