Star Block, Unit B - June 4, 2015

And of course, there's prizes along the way! For last week's prize of the book and patterns, Mr. Random Number Generator chose #2.

Congratulations Kathy! I've sent you an email, so be sure to respond with your mailing info.

This week's prize is sponsored by a wonderful thread company, Aurofil
                                                           Aurifil Italian Threads

They have graciously provided two packs of thread for this quiltalong, and one of them, a 10 spool pack, is the prize this week! Thank you, Aurofil - be sure to show them some love!


And what do you need to do to be entered to win this great prize? Just follow one of these easy steps:

1) write up a blog post with pictures of your blocks and link the post (not your main page) to the linky party at the bottom of this post, or
2) join the Spangled Stars Flickr group here, and post your photo. Click on your photo to get the URL at the top, and link that to the linky party, or
3) post a block photo on Instagram using the hashtag #spangledstarsqal, then link up the URL to the linky party.
Pretty easy! The link stays open for a week, and I'll announce the winner at the next QAL installment. You're welcome to join in anytime, but if a linky party has passed, the chance to win those prizes is also past. Just be sure to post blocks to the next one. Good luck!

Now let's finish up those Star blocks!

Below is the cutting chart for Unit B, the double HST's (half square triangles).

The first HST's are made with the dark blue and white background squares, cut 8 1/2" x 8 1/2". Some quilt sizes will have extra HST's. I'm making the twin size, which has 15 star blocks, each one needing 4 Unit B's, 60 units in all. 



With right sides together,  pair up a dark blue square with a white background square, and mark two diagonal lines from each corner.




Pin them together, and using a scant 1/4" seam allowance, sew along each side of the diagonal line.


It should look like this when it's done.


Time for cutting! A rotating mat works wonderfully for the next step, otherwise do your best to keep all parts together until all the cutting is done. Cut along the diagonal marked lines, then cut lengthwise through the middle, and then horizontally through the middle.


Once all four cuts are made, the HST's can be separated.













Press each HST seam to the dark.

Referring to the chart again, cut the required number of 
3 7/8" strips, then subcut each strip 3 7/8".

















The chart below lists how many squares to subcut for each size.

Mark one diagonal line, corner to corner, on the wrong side of each square. Pair these up with an HST from the previous step, making sure the diagonal line is perpendicular to the HST seam line.


Once again, using a scant 1/4" seam, stitch on both sides of the marked line.



Cut on the drawn line, and press to the medium blue.


Be sure to trim up these little units to 3 1/2" x 3 1/2", aligning the diagonal seams with the diagonal on the ruler.

After trimming, sort the units into two piles, one with the medium blue on the left, the other with it on the right.


Done with Unit B! The next part, Unit C, is to cut the correct number of 3 1/2" strips per the chart below, subcutting each 3 1/2", for the centers of the stars.

Gathering all units, A,B, and C, follow the diagram to lay out the stars for sewing. Use all pieces from one stack of the Unit B's before moving on to the second stack.




This way, there is no confusion because the stars have different rotations. 



If that isn't pleasing, another set of the first dk blue/white HST can be made, or the originals can be torn apart and the dk blue/white positions switched. Personally, it doesn't bother me, so I'm leaving it!

Following my tutorial on Efficiently Sewing a Nine Patch, sew all the stars together, and give them a good press. It's your choice which way the seams go, because they don't have to nest with anything in the final assembly. These blocks measure 9 1/2" x 9 1/2".

Now stand back and admire your work! You did it! Next week I'll go over assembly, and the how the grand prize linky will work. Be sure to link up below with pictures of your Star Blocks for this weeks prize!

Happy Quilting!
