Hello Quilty Buddies,
Here are the detailed instructions for making the Picket Star Block, named because the star points look like slats of a picket fence.
For the 17" finished block.
Fabric A - Two squares 3.5", two rectangles 3.5" by 9.5"
Fabric B - Two squares 3.5", two rectangles 3.5" by 9.5"
I am using medium pink and dark pink. My recommendation is to use two fabrics that have some difference in value - not too close and too much contrast. This will give the look of light and shade.
Stitch the two Fabric A squares (3.5") on either sides of the background square (3.5"), using a scant quarter inch seam. Iron the seams open (personal preference) and trim to 3.5" by 9.5".
Stitch the Fabric A rectangles on either side of the above constructed rectangle, using a scant quarter inch seam. Press seams open and square to 9.5". Set aside.
Step 2.
Stitch the two Fabric B squares (3.5") on either sides of the background square (3.5"), using a scant quarter inch seam. Iron the seams open (personal preference) and trim to 3.5" by 9.5".
Stitch the Fabric B rectangles on either side of the above constructed rectangle, using a scant quarter inch seam. Press seams open and square to 9.5". Set aside.
Step 3.
On the wrong side of the 9.5" background squares, draw lines (pencil or frixion pen), 1/4" from the diagonal.
Place one marked background squares RST with each of the squares completed in Steps 1 and 2. Pin in place.
Sew on the drawn lines. Cut along the diagonal.
You should have four half square triangle blocks. Iron seams open and square each to 9".
Step 4.
Snowball the fabric corners of the HST blocks.
Place the background square (2.5"), RST, on the fabric corner of each HST block. Pin in place.
Sew corner to corner. For accuracy, sew slightly (a thread's width) away from the center, towards the corner of the block.
Cut 1/4" away from the sewing line. Press seam open. Square again.
Step 5 - Final Step
Place the four HSTs (with snowballed corners) such that all snowballs meet in the center. Also make sure that Fabric A is adjacent to Fabric B.
Stitch using a generous quarter inch seam. Yes, I said generous. I suggest moving your needle three clicks to the left to make a generous quarter inch seam. If you can eyeball it, power to you.
It is very important to sew a generous quarter seam because you want to preserve the points in the completed block.
In the pictures below you can see that the point is that much farther away from the edge.
Pin the two halves together for one last seam. Make sure it is a generous 1/4".
Iron seams open and straighten the edges.
The resulting block is just shy of 17.5".
Although there are several steps to making this block, it makes a large block, finishing at 17".
You only need 12 blocks for a lap/throw size quilt (51" by 68")
And 30 blocks will make a queen size quilt (85" by 102")
If you just want to try, I suggest making 4 blocks. It will make a small baby quilt (34" by 34"). Add 3.5" borders to make it larger at about 40" square.
This is the block I am making for my Rainbow Scrap Challenge in 2020. You can see the earlier blocks at the links below.
January - Green Blocks
February - Orange Blocks
March - Teal/Aqua/Turquoise (all the colors between blue and green)
April - Light/Bright Blue

All picket star points are a safe distance away from the edge. This ensures that the points won't get clipped when you put the blocks together, even when you sew a regular 1/4" seam.
