Twinkle2 QAL: Four-patch units and background

Wow...hopefully you got all of your fabric cut and you're ready for some sewing time!!  Grab your stack of 2.5" x 2.5" squares ("B" pieces) for the center four patch.  First, pair up and sew all of the squares together to get little 2.5" x 4.5" rectangle units.  I pressed the seams open since my color scheme didn't really have a "dark" side to press towards...

Then I paired up two rectangles and sewed them together, carefully matching the seams in the center, to make a four-patch unit.  I also pressed the seams open on this part as well....


They should measure approximately 4.5" x 4.5"...but honestly, will will trim down the whole center part when done so if you're a bit off, it won't be a bother at all....

Next, grab the background pieces for these...the "C" pieces.  If you turn your four-patch unit, it will get a diamond shape and become the center among the background half-square triangles.  Because mine were directional, I separated my pieces into the four different corners so I'd sew the correct one on the correct corner.  If your fabric was non-directional (lucky you!!) this step isn't necessary.

First, we will sew a triangle to each of the opposite sides of our four-patch unit.  With right sides together, center the triangle's longest side (the hypotenuse) on the side of the four patch unit--make sure the tip of the triangle aligns with the seam to ensure it is accurately centered.  Sew on the the first triangle, then do the same thing to the other side of the four-patch unit... Press the seams outward (or open) if you prefer...


Trim the tips from the sides of the background triangle by aligning a ruler along the edge of the four-patch unit and cutting.  Next, we will attach the other two triangles to the the unit.  Remember to align the tip of the triangle to the seam in the four-patch unit to ensure that the triangle is centered correctly.  Press the seams outward....


Now to square this baby up!!  Grab a 6.5" x 6.5" square ruler (if you have one, if not, you can use a bigger one)...Lay the ruler on top of the square, aligning the corners of the four-patch unit with the 3.25" marks on the ruler.  All four corners should be at 3.25" (or as close as you can get).  Trim outside of the ruler to get your 6.5" x 6.5" square.


Voila!!  You have the center part of the block done...there will be (in all likelihood) more than 1/4" of background fabric beyond the tips of the four-patch unit.  That is how it is supposed to be..the four-patch will sort of "float" (though not very noticeably) in the middle of the 6.5" x 6.5" square.  See, there really is room for a bit of error if you aren't very exact ;-)  Yeah!!

On August 9th, we will learn to make the star tips and get the basic block done (without the sashings)...get working!!  I'll see you back soon....
