Block layouts, EPP templates, Lone Star drafting.
Quilters reach Grid Maker Pro for four geometric grids the craft depends on. Square for traditional block layouts. Hexagonal for English Paper Piecing — Grandmother's Flower Garden, hexie quilts. Triangular for half-square triangles and flying geese. Diamond for Lone Star and argyle-influenced patterns. Plan the quilt block by block, hex by hex, before any rotary cutter touches the fabric.
Four block geometries, four overlays.
Every traditional quilt block reduces to one of four grid geometries. The nine-patch and log-cabin live on the square. The hexie flower lives on the hexagon. The flying-geese strip lives on half-square triangles. The Lone Star lives on the 1:√3 diamond. Pick the geometry first and the fabric maths follow.
Nine-patch
Three by three. The quilter's first block — equal-size squares, no fancy cuts.
Log cabin
Centre square, light side, dark side. Half a cabin in shadow.
Grandmother's flower
One centre hex, six petal hexes. The English Paper Piecing icon.
Lone Star
Eight diamonds radiating from a centre. 1:√3 aspect. Drafted from centre out.
From sketch to seam in four moves.
The grid is what your sketch and your fabric have in common. Set it once at the block's finished size, print at 1:1, and the template you cut to is the size your seams will land on.
Sketch the colour layout
Block by block on grid paper or screen. Decide warm/cool, light/dark, focal points.
Set the cell dimension
Inches or centimetres. Match your finished block size — 3″, 4″, 6″, 12″.
Print at 1:1
PDF export to US Letter or A4. No fit-to-page — the printed cell is the finished cell.
Cut & piece
Add ¼″ seam allowance to the cut. Stitch on the template line. The grid finishes flat.
Six fabrics that render most heritage quilts.
A Liberty floral. A petrol stripe. A mustard polka-dot. A leaf-green check. A cream ground. A Japanese taupe. Six bolts will quietly produce a great many quilts — once the geometry is set, the colour decisions are about contrast, not catalogue.
The quilter's overlay set.
Hexagonal Grid
English Paper Piecing templates at any inch or cm size.
→Triangular Grid
Half-square triangles, flying geese, kaleidoscope blocks — equilateral tessellation.
→Diamond Grid
Lone Star, Bethlehem Star, argyle-influenced layouts.
→Square Grid
9-patch, 16-patch, log cabin, traditional N×N block layouts — quilt graph paper at any cell size.
→Golden Ratio
Proportional border widths and centre-block sizing.
What quilters actually use it for.
For Grandmother's Flower Garden the hexagon paper has to be identical to within a thread. I print my EPP templates at 1-inch finished on US Letter, six sheets per project — the consistency is what makes the petals sit right against each other when you whipstitch.
Lone Star at 1:√3 — there's no other way. I draft the diamond from the centre out before any rotary cutter comes near the fabric. The eight star points either meet cleanly at the centre or the whole quilt reads wrong, and you can only see that on paper first.
For modern improv I work to a loose 4×4 layout but I plan colour over the grid first, every time. Even improv needs a scaffold — knowing which sixteen cells are warm and which are cool decides the whole quilt before I cut a single strip.
The questions quilters ask.
Can I print grids at quilting scale?
Yes — every grid exports as PDF at any paper size, and you can set the cell dimension in inches or centimetres directly to match your block size. A 12-inch quilt block printed at 1:1 scale on US Letter paper, a 6-inch hexagon for English Paper Piecing — set the dimension once and the printable matches the cut size of the fabric.
Which grid for English Paper Piecing?
The hexagonal grid for traditional Grandmother's Flower Garden (1-inch or 1.5-inch hexagons are standard). The diamond grid for Lone Star and argyle-influenced patterns. The triangular grid for tessellated half-hexagon piecing. EPP relies on accurate, consistent paper templates — Grid Maker Pro produces them in any size.
Does the grid include seam allowance?
No — the grid itself shows the finished size. For seam allowance, add the standard ¼ inch (6mm) to your cell dimension when cutting fabric, so the printed paper template represents the sewn edge, not the cut edge. Most modern quilters use ¼ inch by default; English Paper Piecing typically uses ⅜ inch for added handling room.
Which grid for half-square triangles and flying geese?
The triangular grid. Half-square triangles and flying geese both tessellate on a grid of equal triangles, so you set the cell to your finished unit, print at 1:1, and the template lines mark where the diagonal seams fall. Add the ¼ inch seam allowance to the cut as usual.
Which diamond grid is right for a Lone Star quilt?
The 60° diamond grid. A Lone Star is eight diamonds radiating from the centre at a 1:√3 aspect, so drafting the diamond grid from the centre out lets you check that the eight points meet cleanly before any rotary cut. The same diamond grid handles Bethlehem Star and argyle-influenced layouts.
