Snap a photo or sketch and Frog and Thread turns it into a clean, printable quilting stencil — tiled across pages with true 1/4" seams. Design, print, and stitch. Frog and Thread turns any photo, drawing, or idea into a quilt-ready stencil you can print at home and stitch with confidence. Point your camera at a sketch, a flower, a child's drawing — anything — and our pattern maker converts it into clean, transparent line work. Or design from scratch in the Quilt Studio with math-native vector blocks. Either way, every line is measured in real inches, so your seam allowance stays a precise 1/4" no matter how you scale or print. WHAT YOU CAN DO • Photo to pattern — capture an image with your camera and turn it into a printable stencil in seconds. • Quilt Studio — drag, scale, rotate, snap, and tile blocks on an inch-accurate canvas. • True 1/4" seams — bleed and seam allowance stay mathematically constant at any quilt size. • Print-perfect tiling — your design splits cleanly across letter or A4 pages, ready to tape and trace. • Classic blocks, done right — half-square triangles, LeMoyne stars, nine-patch and more, built from real quilting math. • The Pattern Book — browse, buy, and sell patterns quilter-to-quilter, resizable and ready to piece. • Your projects, organized — every design saved to your workspace, ready to revisit and reprint. BUILT FOR QUILTERS Whether you're a longarm professional, a pattern designer, an educator, or piecing your very first quilt at the kitchen table, Frog and Thread keeps your measurements honest and your prints accurate.
