Twin Star quilt block

Star blocks are fun to make and the one I am going to show you today is definitely a pretty one. It is called Twin Star and created as a nine-patch so goes well with other nine-patch blocks. By the way, this would be a great addition to the border corners of Anita's Entwined Star quilt pattern when made as a 6" finished block.

Twin Star

Being a nine-patch (3 squares across and 3 squares down), it is best made up in sizes divisible by three. The most common being 6", 9" and 12". You could also work it in 4 1/2", 7 1/2" and 10 1/2", but that gets a little more tricky.

There are several methods to make the Twin Star Block. The method I will use ensures that the straight of grain is around the outer edges of the block. This prevents the block from losing shape and reduces stretching when joining blocks together. 

For each star block you will need the following squares in each of the three common sizes:

 

6"

9"

12"

background fabric

ONE 3 1/4" sq
FIVE 2 1/2" sqs

ONE 4 1/4" sq
FIVE 3 1/2" sqs

ONE 5 1/4" sq
FIVE 4 1/2" sqs

medium fabric

ONE 3 1/4" sq

ONE 4 1/4" sq

ONE 5 1/4" sq

dark fabric

 TWO 3" sqs

 TWO 4" sqs

 TWO 5" sqs

Tip: If you want to make an entire quilt, just times the above numbers by the number of blocks you want. Or if you want to make FOUR blocks for border corners such as Entwined Star times the amount by four. For example: To make FOUR 6" finished blocks you will cut FOUR 3 1/4" and TWENTY 2 1/2" background squares, FOUR 3 1/4" medium squares and EIGHT 3" dark squares.

Step 1: Cut the medium fabric square through the diagonal twice. Do the same with the same size background squares. If you stack them on top of each other carefully so all raw edges are even, you can cut these together. It helps if you cut the squares together first.

Cut quarter square triangles

Step 2: Cut both the dark square in half through the diagonal once.

Cut half square triangles

Step 3: Join the small triangles together using a 1/4" seam along one short edge ensuring they are all joined the same way. For example: sew with the background triangle on top. Start stitching from the square end of the triangle. Press seam toward the medium fabric.

Small triangles are joined along one short edge

First pair joined - make 4

Step 4: Match unit made in Step 3 to dark fabric triangle along long sides. Make a slightly smaller than 1/4" seam here as this gives you room to trim evenly.

Making star point units

 Step 5: Trim unit to size using a square ruler. That is 2 1/2" (for 6" block), 3 1/2" (for 9" block) or 4 1/2" (for 12" block). Align ruler so that diagonal ruler line is aligned with small seam and 1 1/4" (or 1 3/4" for 9" block or 2 1/2" for 12" block) point is where seams meet. Along the sides of the ruler, the correct size for your block should be positioned on the seam. That is 2 1/2" for 6" block and so forth.

Trim matching lines on ruler with seams

Step 6: Rotate block and trim remaining two sizes aligning evenly again. Finished unit will measure 2 1/2" for 6" block. (3 1/2" and 4 1/2" respectively for 9" and 12" blocks)

Trim remaining sides

You will make FOUR of these units.

Star point units completed

Place the units on your design wall or cutting board and position with plain background squares in each corner and center of the block. Rotate each star point one quarter turn and position in the appropriate places.

Position squares and star points in rows

Sew these pieces in rows and press seam towards the background square so seams butt together when joining rows.

Join rows and give a good overall press.

Finished Block

This was a fun block to make and didn't take long at all. You could also add a colored square to the center instead of a background square. Next week I will make another star block so stay tuned and remember to share my page on facebook if you like.
