QuiltSandwich helps with quilt math and
keeps track of the details so you can stay in your creative zone

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.
Print or Share project.
Print when you're ready. Share as a PDF or PNG. Share project with another quilter who has QuiltSandwich.

Standard Features

  • The Yardage Calculator figures yardage using the Finished Size and Number of Pieces for Rectangles or Squares, Triangles (Half-Square, Quarter-Square, Corner, Side Setting, Half Rectangle), Sashing, Borders (Horizontal, Vertical or Mitered), Binding (Straight-Grain or Bias), Backing (Best Fit, Vertical, or Horizontal), and Batting (Best Fit, Vertical, or Horizontal). Fabric needed is given in Yardage or number of Fat Quarters. Settings for Seam, Shrinkage, Selvage and Cut Edge allowances can be adjusted. There are two cutting diagram layout settings, find least yardage or force layout to piece width on 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.)
  • Fabric images are added from device camera. Fabrics can be added immediately to a project or added to the Fabric Stash and later assigned to projects. Fabric images can be compared side-by-side by swiping image tiles.
  • Layouts defined in QuiltSize app can be exported to QuiltSandwich. As part of the import all the pieces, including binding, backing and batting are added. Replace the placeholder blocks with the block pieces to complete yardage requirements.
  • Pixel Quilts designed in ColorHints Mosaic app can be exported to QuiltSandwich. As part of import the piece size is set so that QuiltSandwich can create a Journal with the pattern. Pieces are listed with placeholder color tiles and yardage for fabric.
  • Share and Archive tool offers two features. One, a way to Share a QuiltSandwich pattern to another QuiltSandwich user or share to another device using email. Two, a way to Archive a project off the iPhone or iPad and save it to iTunes.
  • App Images manager tool deletes images imported into QuiltSandwich that are no longer needed in the app. It does NOT affect images in the Photo Library.
  • No ads.
