Disappearing nine patch...with a twist!

My state guild, Land of Lincoln Quilting Association, conducts block swaps, like many other guilds.  The newest block swap is based on a disappearing nine patch.

Our instructions are to start with 9 different batiks, cut into 8" squares.  From 9 fat quarters, I was able to get enough for 4 blocks.  With the left over fabric, I cut out 5" squares, enough for 3 blocks.

Sew them into a nine patch.  Colour arrangement is personal preference.

Then cut the nine patch in half vertically, then horizontally.

Here's where the twist comes.  Take one of the newly formed blocks, and lay it over another block, right sides facing.  The key is to have your small squares in opposite corners.  Repeat for the remaining two blocks.

Pin the blocks together to avoid slippage, then sew around the block on all four sides.  Repeat for the last two blocks.

Then cut your sewn block diagonally (from corner to corner) twice to create four new blocks.  Repeat for the second block.  Then press open!

Voila!  You get a very complicated looking block with very little work.  And certainly endless combinations to work with placement.  And the colours will change dependent upon how you arrange your initial 9 squares!  Each original 9 patch generates 8 blocks that measure around 8 1/2" unfinished.

Isn't this fun!
