Using a quilting technique for symmetry art

This was all my girlfriend's idea.  She'd subscribed to a quilting magazine and  used an idea to show her daughter's art teacher.  Then we all had fun creating these together.  It's a fun way of learning symmetry, some fraction concepts, positive and negative images .. and I'm all for the thought processes being engaged in creativity.

To start with, you need a white page for background, then a colour page, where colour is on both sides, preferably.

If the page is A4 (as mine is), then diagonally fold so you get a square and cut off the excess.   Then fold again to form quarters.

Open the page out.  In each triangle, freehand draw or rule 3 lines.  Yes, it needs to be 3, but it can be any shape you like.  Here I have done triangles.  You can do semicircles, 1/2 flowers, 1/2 hearts .. lots of ideas.

Cut out along each line.  The centre which is left is then pasted onto the background page diagonally.

Working on one of the cut-out areas at a time, take the largest piece and flip it over so it lines up on the corners to the area from which it was taken:

Now take the second piece and place that back inside the cut-out area, also lining up the corners.  Repeat with the smallest / final piece.

Continue with all sides and you'll get this lovely pattern:

Experiment and see what lovely patterns you can create:

If you do use this idea for quilting, you need to fix interfacing to the back of each shape and iron them into place.  Secure it all with crazy quilting.
