8-1/2" Squaring Up Ruler & 8" Fussy Cutter - Marti Michell

8-1/2" Squaring Up Ruler ..... includes left and right handed cutting instructions. 

1. A shadow follows each inch line and turns a corner to make it very easy to see squares.
2. Numbering out from one corner on two sides.
3. Align the 45 degree diagonal line with the seam line to square up half square triangle units.
4. Four distinct line styles for 1/8", 1/4", 1/2" and 1" increments.
5. Every line has spaces so you can align the cut edges of the fabric with the line, not on one or the other side of a line.
6. The last 1/4" is clear on two sides to easily check 1/4" seam allowances.
