Template plastic with a printed 6 mm (¼ in) grid to align angles, replicate blocks and draft patches accurately. Sheets measure about 280×215 mm (11×8½ in), accept pen or pencil and cut cleanly with scissors or a craft knife. The lightly textured surface resists slipping on fabric while tracing. Two-sheet pack is perfect for planning applique, English paper piecing and custom rulers. Remove promptly after sewing to keep surfaces residue-free and fabric-friendly.
