	Multi-Patch, Inc. “Zero Math & Square on Point Quilt Rulers”

Most Traditional Quilt Blocks are comprised of: Square, Rectangle,
Half Square Triangle, Quarter Square Triangle and Square on Point Patches.

To read a block first identify each individual Patch Type within the block.
Then simply estimate what portion of the block each individual patch spans (1/2, 1/3, 1/4 etc).

The Diagram below shows
each patch type and the portion of the block each patch spans.

Once you are able to read a block you will be able to create the block
without a pattern. You also will be able to create or design your own block.

Patch Type Abbreviations

HSR = Half Square Rectangle
HST = Half Square Triangle

	Cut strip/s for QST - Place the QST cutting edge on the fabric and position the appropriate Dash Line (2) on the edge of the fabric.


	Cut Square/s for QST - Place the HST cutting edge on the fabric strip and position the appropriate Dash Line (2) on the short edge of the fabric. You need 1 of these square (4 QST patches) per block.


	Diagonally Cut QST - Corner to corner twice creating 4 QST patches


	Cut strip/s for HST - Place the HST cutting edge on the fabric and position the appropriate Dash Line (4) on the edge of the fabric.


	Cut Square/s for HST - Place the HST cutting edge on the fabric strip and position the appropriate Dash Line (4) on the short edge of the fabric. You need 2 of these square (4 HST patches) per block.


	Diagonally Cut each Square creating 2 HST patches


	Cut strip/s for SQ - Place the SQ cutting edge on the fabric and position the appropriate Dash Line (4) on the edge of the fabric.


	Cut Squares - Place the SQ cutting edge on the fabric strip and position the appropriate Dash Line (4) on the short edge of the fabric. You need 4 of these SQ patches per block.


	Cut strip/s for SOP - Place the appropriate SOP cutting edge on the fabric and position the appropriate Dash Line (2) on the edge of the fabric.


	Cut Squares for SOP - Place the appropriate SOP cutting edge on the fabric strip and position the appropriate Dash Line (2) on the short edge of the fabric strip. You need 1 SOP patch per block.


	Cut strip/s for HST - Place the HST cutting edge on the fabric and position the appropriate Dash Line (4) on the edge of the fabric.


	Cut Square/s for HST - Place the HST cutting edge on the fabric strip and position the appropriate Dash Line (4) on the short edge of the fabric. You need 4 of these square (8 HST patches) per block.


	Diagonally Cut each Square creating 2 HST patches. You need 8 HST patches per block.

Assemble SOP Unit - Finger fold the SOP patch in half side to side creating a crease. Finger fold the SOP patch in half again using the other two sides creating a second crease. Position the HST patch face to face with the SOP so that it long edge is on one side of the SOP patch. Place the point of the HST on the SOP crease. Sew a 1/4” seam along the edge. Repeat for the other 3 sides.


	Assemble Flying Geese Unit - Place QST and HST face to face so that the long side of the HST is aligned along one of the short sides of the QST and the short side of the HST is aligned on the long edge of the QST. The points of the HST and the QST should match. Sew a 1/4” seam along the long edge of the HST.


	You need 4 Flying Geese units per block




	You need 1 SOP unit per block.


	Assemble patch units in rows than sew rows together.


	Row 1

		Row 2

		Row 3
