It’s All about Triangles & Quilting!

We pay homage to one of the cornerstones of quilting – the lowly triangle!

Three sides, three angles, three major descriptions of triangles.

**1. Scalene triangle**

- 3 different length sides
- 3 different sized angles
- typically used in setting triangles
- easier to paper piece
- no lines of symmetry – cannot accidentally flip the block over to fix a mistake
- can be a right triangle (one angle = 90 degrees)
- typical triangle found in math class 30, 60, 90
- can be called half rectangle triangles in quilting

Found in:

- tilted blocks (as setting triangles)
- wonky blocks
- mariner’s compass blocks
- palm blocks
- birds of paradise blocks

Eye searing pink blocks are just SOME examples of scalene triangles in these blocks.

**2. Isosceles traingle**

- 2 equal length sides
- 2 equally sized angles
- most commonly found in quilting
- Half Square Triangle – HST
- Quarter Square Triangle – QST
- one line of symmetry, flip around the ‘odd’ angle
- can be a right triangle (HST, QST, flying geese)
- how you cut could have one bias edge (the hypotenuse) or two (the shorter legs)
- typical triangle found in math class 45, 45, 90
- triangle with an acute ‘odd angle’ – kaleidoscope block

Found in:

- pinwheel
- broken dishes
- flying geese
- ohio star
- hourglass
- square in a square
- friendship star
- spool
- maple leaf
- kalidescope …..

Look for the black triangle to see some of the isosceles triangles in these quilt blocks (there’s many many more)

**3. Equalateral triangle**

- 3 sides equal length
- 3 equally sized angles
- least commonly found in quilting
- 6 triangles can make a hexagon block
- all angles are 60 degrees – no exceptions
- 3 angles of symmetry, flip around any angle
- guaranteed to have 2 sides of bias edges

Found in:

- thousand pyramid blocks
- chevron designs
- strip pieced hexagons
- tumbling blocks
- bordered thousand pyramid blocks

Hmm

Look at the ~~yellow ~~any block to see the equilateral triangle (assuming the image doesn’t get squished somewhere)

Working on periodic spiral quilt – mostly basted, now need sewn together

Need an outline behind the spiral for it to stand out from the background

Exothermic quilt - see previous post about my place on this quilt as of a week ago.

Exothermic quilt on point:

Design decisions to make on the exothermic quilt:

- Borders are GOOD – do NOT fix them
- On point or not?
- If so, have to fix coping black/ grey inner border
- How much more black fabric to buy?
- Paralllelograms in the middle stay or go? – it provides good movement, but too much of a distraction??

HAVE YOU SEEN:

- a 5 x 8 sized graph paper notebook for sale? If so, what brand, where are you finding them, have you seen them online?
- I would love a notebook this sized to carry around more easily!

A MUST HAVE book for anyone wanting to hand / machine quilt with specific designs:

501 Quilting motifs: Designs for Hand or Machine Quilting from the editors of Quiltmaker Magazine

- Takes one motif and slightly changes it, multiplies it, rotates and flips it,
- gives dimensions on block size for motif found in book.
- looks easy to trace and adapt
- great resource
- hardbound
- spiral inside

If you want to Swap Charm (5 inch) squares, go to this swap on Swap – Bot:

I’m willing to join if there is a good & healthy number of people in the swap!

You have until Sept 2, 2011 to make your decision!
