Sew. Happy. Quilt. QAL Tutorials: Friendship Star & QST Pinwheel Blocks

Welcome to the fourth week & second tutorial of Sew. Happy. Quilt. QAL! I’m so glad you’re here! If you haven’t joined yet but are interested, this is the Flickr group and here’s the QAL info page with all the other links. This is the last week that we’ll be doing two blocks in one week, and they’re pretty easy so anyone can join at anytime.

Quick Note: I use starch enthusiastically when piecing. I starch everything after I’ve cut it. If I leave it overnight, I starch it again before sewing with it. It literally brought my piecing from zero to hero. So go get some. Use light coats, and iron it in. Small pieces of fabric are much easier to handle when they’re a bit stiff. And no, it doesn’t hurt your machine, or fabrics, or quilt.

Let’s tackle the Friendship Star first:

For this block you’ll need at least 3 fabrics. The number of squares and their measurements are above. You can set aside those 4.5″ squares for now, as we’re going to make HSTs (Half Square Triangles) with the 5″ x 5″ squares first:

Take two of your squares and draw (in pencil) a diagonal line DOWN THE BACK (not the front!!!) and then draw additional lines 1/4″ on either side as shown above. Then lay those RST (right sides together) with your other 5″ squares – if you look at the one on the left you can see the aqua square just peeking out.

 Sew on the 1/4″ lines you drew. In all you’ll do 2 seams per square. Then cut carefully along that middle diagonal line, as shown on the left. When you open them up and press the seams, they’ll look like the ones on the right.

A WORD ABOUT HSTs: Here’s the deal. If you want your HST to be, say, 4″ finished, you need to use squares cut one inch larger (it’s a little more complicated than that, but let’s not go there). Then, after you open them and press the seams, you need to trim them down to a perfect 4.5″. If you’re puzzled about trimming, there’s a picture in the next block that shows what I mean. Once you see the pic you’ll get what I’m on about. Honest.

 Now line up your HSTs and your 4.5″ squares so they look like this.

  Then sew them together in rows like this. Make sure your 1/4″ SA is as near perfect as possible so they line up in the next step.

Then sew the rows together to make your Friendship Star! Woohoo!

Now on to the QST Pinwheel Block:

 You’ll need 3 different fabrics for this one as well – and 4 squares in all. The measurements are above. I got ahead of myself and also cut my 7″ x 7″ squares on the diagonal. You can go ahead and do that too.

Now take your 7.5″ x 7.5″ squares and cut them diagonally. Cut them again diagonally to reveal 4 little triangles. CAUTION: You are now exposing the bias (horror!!) and therefore need to proceed carefully. Don’t pull the triangles in any direction. Do not steam. Do not rub back and forth with the iron. Starch like crazy if you have starch (or sizing, etc). Like 2 or 3 coats on the back of the fabric. That way your fabric and the bias will behave and perfect points will be MUCH easier to achieve.

 Lay your pieces out as shown above.

 Now sew those smaller triangles at the point shown above. Sew all 4 sets and press seams {open or whatever you prefer}. Lay them back in the formation, because it looks pretty and you’re proud.

 Here’s the back of mine for educational purposes. I press open. Because I’m a rebel.

 Ok, now you want to attach your seamed triangles with your unseamed ones (aqua in my case). Then open them up and press seams.

Le Pic De Trim: This is what you’ll end up with. Now, see how much I trimmed away? You pretty much have to trim down to exactly 6.5″ x 6.5″ if you want your points to line up. Lining up the diagonal with the line on your square ruler is good too.

And sew it all together. That’s it.

P.S. I’m sure there’s an easier way to make them, but it’s only one block so I did it this way.
