READ NOTES AND INSTRUCTIONS BEFORE GETTING STARTED
NOTES
• All calculations have been tested for accuracy.
• All measurements are in inches.
• All instructions assume a basic knowledge of rotary cutting.
• For your reference, the formula for each block is under the block name on the calculator.
DEFINITIONS

• All instructions assume a basic knowledge of rotary cutting.
• For your reference, the formula for each block is under the block name on the calculator.
DEFINITIONS
Finished Block
• Block dimensions after it has been sewn into a quilt.
Unfinished Block
Unfinished Block
• Block dimensions before it has been sewn into a quilt, i.e. finished block dimensions plus seam allowance.
Parent Squares
Parent Squares
• The squares you make using the formula. These squares are used to build your block.
Square Up
Square Up
• Trimming a block to its correct size.
TIPS FOR MAKING PERFECT BLOCKS
• Round up uneven results to the nearest even fraction or round number.
I use this handy decimal to a fraction conversion table.
• Double-check your results before cutting your parent squares.
• Make a test-run block before cutting your good fabric.
• Cut the parent squares accurately.
• Use a scant ¼ inch seam allowance to make the block slightly larger and easier to square up.
INSTRUCTIONS
1. Scroll down to find the block you want to make.
2. Depending on the formula, enter finished or unfinished block size you need.
3. Find the parent square size(s) in the orange box. If required, round up the result.
4. Cut the number of parent squares required.
5. Follow the assembly diagrams provided on the calculator to make the block.
6. Square up block if necessary.
