QuiltSandwich handles quilt math and keeps track of project details

so you can be in your creative zone

Download QuiltSandwich app for iPhone & iPad from App Store
Start with a quilt design.
Quilt designs come from many sources — historic quilts, found patterns, purchased quilt kits, or an inspired design of your own creation. Whatever your starting point,  QuiltSandwich supports much of the preparation effort for quilt projects.
Just to be clear — The QuiltSandwich app is not a quilt designer. It does not provide block designs.
There are marvelous resources available to quilters to design quilts and blocks — from fancy quilt design programs, to specialty graph paper designers like QuiltPaper, to books, to treasured antique quilts.
Enter pieces and fabrics.
QuiltSandwich works with finished sizes so you can pull dimensions directly off designs, patterns and kits. Cutting diagrams show you how to fold and cut the fabric to get that number of pieces from the yardage or FatQ.
Cut fabric with confidence.
Cut knowing the fabric choices are right and the yardage for pieces, binding, backing and batting will be:
  • Enough to cut and sew using your favorite methods.
  • Enough to create the quilt in a kit.
  • Enough after tweaking this pattern to a larger or smaller size.
  • Enough.

How will YOU use QuiltSandwich?

QuiltSandwich is the tool box quilters want because it was inspired by a quilter.
  • Some quilters use QuiltSandwich's Yardage Calculator to confirm kit instructions because it creates a cutting diagram that shows you how to get the number of pieces promised.
  • Many quilters use QuiltSandwich at the cutting table to better estimate how much yardage to buy.
  • Quilters use it for fabric selection because QuiltSandwich's digital library lets you carry with you all your fabric clippings on your iPhone.
  • QuiltSandwich gives quilters confidence to make the leap to plan to creating their own quilt designs because it handles the quilt math and creates cutting diagrams that help confirm plans before cutting.


Unique notions with QuiltSandwich

QuiltSandwich replaces yardage tables, formula charts, and envelopes of fabric clippings with a set of tools that are always available on your iPhone or iPad.


Calculators you can trust

Cutting Diagram shows the yardage calculator's assumptions on how to fold and cut fabric to get the number of pieces needed — as well as show the size and amount of scrap to expect.
SIZE IT! helps you resize projects. Enter an original side length and the desired length to get the percentage size change.

Help with fabric selection and purchase + Compare tool

Fabric Stash lets you take your fabrics with you. Just snap a picture to add, compare, and manage swatches.
Color Mix displays the proportion of colors of all the fabrics in the quilt top fabrics including binding. It is a way to check a quilt top's color balance before fabric purchase (or cutting)!

  • The Yardage Calculator has two cutting diagram settings, find least yardage or for one-way fabrics force layout to crosswise grain.
  • Yardage is calculated for each unique piece shape. (When a fabric is used by multiple pieces, it may be possible to purchase less fabric by considering the scrap shown in the individual cutting diagrams.)
