Quilt Builder: Design & Stash

Design quilts, organize your fabric stash, and plan every cut.

Quilt Builder is the all-in-one companion for quilters — capture your fabric, design blocks and quilts, and know exactly what to cut before you reach for the rotary cutter.

Quilt Builder is free to use — design quilts, catalog your stash, and get cut lists without an account. An optional Premium subscription removes the free limits and unlocks the power features, including designing your own blocks from scratch.

DESIGN FROM A CATALOG
• Start from a library of traditional blocks — half-square triangles, friendship star, log cabin, and more.
• Give each section of a block its own fabric, then arrange blocks on a snap-to-grid layout.
• Rotate, flip, and set blocks on point. Scale a design up to throw, twin, queen, or king size quilts.

CATALOG YOUR FABRIC STASH
• Snap a photo of each fabric and carry your whole stash in your pocket.
• Set true-to-life scale with the printable calibration card or by hand, so swatches show at real size.
• Add the details that matter — brand, designer, line, yardage owned, where you bought it, and notes.
• Flag fabrics that are running low, and see total yardage and estimated stash value at a glance.

KNOW WHAT TO CUT
• Every quilt generates a cut list with pieces and yardage, including a sensible overage.
• Share it so it's right there with you at the cutting table.

PRIVATE BY DESIGN
• Your fabric photos are processed entirely on your device — they never leave your phone.
• No ads. No analytics trackers. Sign-in is optional and only unlocks premium extras.

PREMIUM — OPTIONAL SUBSCRIPTION
Everything above is free, with generous limits (20 swatches, 15 blocks, 5 quilts). Premium adds:
• Design your own blocks from scratch — draw on a snapping grid, let the app find the regions, fill them with your fabrics, and save it as a reusable block.
• Unlimited swatches, blocks, and quilts.
• Cloud backup and restore, so your stash and designs survive a new phone.
• Full fabric detail fields for serious stash organization.
• Export a high-resolution image of your finished quilt.
