NOTE: The QUILTSANDWICH app is not a quilt designer and it does not provide block designs. There are marvelous resources available to quilters to design quilts and blocks — from fancy programs to graph paper to the QuiltPaper app that lets you make your own custom papers to books to treasured antique quilts.

Toolbox 2 — Yardage Calculator

quiltsandwich yardage calculator

Calculator for Quilt math with Yardage shown in cutting diagrams

  • Take sizes right off the design because finished sizes are expected by the calculator and it adds the seam allowance for you as it figures yardage​
  • Avoid over spending on fabric by using the Yardage Calculator at your LQS cutting table or when shopping online
  • Consider your construction methods as you review the strips, pieces, and cut size in the cutting diagram
  • Adjust piece size to check yardage needed to cut oversized pieces
NOTES ABOUT THE CALCULATIONS:
  • Yardage Calculations are rounded up to the nearest 1/8 yard.
  • The yardage for each piece is calculated independently. So, if the cutting diagrams show 'good size scraps', review them carefully to look for opportunities to adjust allowances and buy less fabric overall.
  • When Least Fabric is selected, calculations are run twice in the background, first orienting pieces in one direction and then the other. The layout that uses the least fabric is shown.

  • ​When a piece is assigned a different fabric, fabric amount available is updated for BOTH the original fabric (it is added back to the stash) and for the new fabric choice (it is subtracted from the stash.)
  • If you are working with cut sizes enter the piece cut size AND set the seam allowance to zero. This is explained further in the blog entry, "What if you only have cut sizes to work with?"

​

NOTES ABOUT THE CALCULATIONS:
  • Yardage Calculations are rounded up to the nearest 1/8 yard.
  • The yardage for each piece is calculated independently. So, if the cutting diagrams show 'good size scraps', review them carefully to look for opportunities to buy less fabric overall.
  • When Least Fabric is selected, calculations are run twice in the background, first orienting pieces in one direction and then the other. The layout that uses the least fabric is shown.
  • Because piece finished sizes are expected by the Yardage Calculator take piece sizes right off your design — the QuiltSandwich app adds the seam allowance for you as it figures yardage.
  • If you are working with cut sizes enter the piece cut size AND set the seam allowance to zero. This is explained further in the blog entry, "What if you only have cut sizes to work with?"
  • When fabric price per yard is entered, QuiltSandwich will calculate the cost for the total amount of fabric yardage used. When the same fabric used for multiple pieces, the cost for the total purchased yardage or FatQuarters is shown in Fabric Stash.

​

Toolbox 3 — Fabrics

quiltsandwich fabric stash

Fabric in your stash or separated by project

Adds fabric with a camera snap — and you've always got your swatches handy!
  • ​Adjust allowances in the Fabric Stash to squeeze more pieces out of a piece of fabric.
NOTES ABOUT ADDING PIECES:
  • Add a fabric with either a snap of the camera or take a screenshot of an internet fabric.
  • If you are working with cut sizes, instead of finished piece sizes, go ahead and enter the piece cut size AND set the seam allowance to zero. This is explained further in the blog entry, "What if you only have cut sizes to work with?"
  • When fabric price per yard is entered, QuiltSandwich will calculate the cost for the total amount of fabric yardage used. When the same fabric used for multiple pieces, the cost for the total purchased yardage or FatQ is shown in Fabric Stash.​
