Scrappy Pinwheel in a Square

Scrappy Pinwheel in a Square.

Three challenges in one!  I’m so excited to share this new block with you all!  Making a pinwheel block is a challenge, but then so is a square in a square block, – cutting all those extra triangles and then getting them lined up.  More often than not these blocks would need squaring up as well, creating an extra challenge.  Well this is super easy!  There are no triangles to cut.  I’ve bypassed these issues to bring you a new way of construction.  This is a terrific block for scraps.  You can use any kind you like, the more the merrier.

You may remember recently I shared the Double Pinwheel Block Easy Scrappy Style.   Do you remember when Jenny Doan showed us how to make a pinwheel block using two squares.  This was my inspiration!  I explored other options of what else can be done using the same principal but adding a four patch unit instead.

Well, I’ve taken this a step further to create this delightful block which looks complex but is really very easy to put together.  In order to get a uniquely scrappy effect you will make two blocks at a time.  This is good as you can chain through each pair of blocks.

There are just two things to be careful of.  Please observe the quarter-inch seam allowance and be aware that you will be dealing with bias seams, so treat them gently until they are incorporated into your quilt.

So let’s get to it!

Ingredients for Two blocks

8 x 3 1/2″ squares – make sure each one is quite different, I’m using medium to dark squares
2 x 6 1/2″ background squares light coloured

To Assemble Two Scrappy Pinwheel in a Square Blocks
From the eight 3 1/2″ squares make two groups of four and then sew into four patches.  Make sure that the centre seams are well aligned.  Press the blocks.  Incidentally you will see that my seams are a little puckered.  That is because my stitch length was to small and there was some tension on my thread.  I’ve corrected that.

Now place a four patch block, right sides together with one 6 1/2″ background square. Pin gently to hold in place.  Sew a 1/4″ seam all around the edge of the block for the whole perimeter.  Repeat with the second four patch and background square.  Just as a matter of interest I’m sewing with a Singer 15 C 1902 treadle.  You can read more about how I got this one going here.

Now take the two sewn blocks to the cutting board.  Align the ruler diagonally across one of the blocks and carefully cut.  Cut with the four patch side towards you to line up the centre.  Repeat for the other diagonal, then do the same with the other block.  Now you will have eight units.  Separate them out so that you have two sets, each with four different units.  Arrange them with the scrappy units in the centre and the background square in the outer corners as shown.

Be sure to remove the extra pieces of dog ears from the centre and this will assist in your block sitting nicely in the centre.  Trim the dog ears and  press.  Now you will have eight delicious units like this.

Assemble them into the two blocks making sure that no fabric is repeated in each block.  It’s a bit of fun!

Now sew the units together like a four patch.  Sew slowly at the point.  Pin if necessary and ensure that the seams line up.

Now you will have these two lovely units.  Press carefully.  I’ve been making some more.  By the way, I’m planning to make a baby quilt with these.  Stay tuned as in a future post I will be showing how I finish these blocks to stabilise them.

Unbeknowns to me I’m am now aware that this unit of construction is also called a Boston Block, thanks to Preeti at Sew Preeti Quilts!  She had also come up with a similar idea of this method of construction.  Please do check out her tutorial at Boston Block Tutorial http://sewpreetiquilts.blogspot.com/2014/04/four-patch-hst-boston-block-tutorial.html.  She also has some other great ways of using and placing these blocks!  This is great as she uses 5″ Charm Squares to achieve the same block.  More excellent ways to use up those leftover charm squares to make a scrappy quilt!

Have a wonderful Quilty Day!
