Let's Make a Pinwheel Block

If you're coming to the Pinwheel Party, this will be good practice.

We'll start off with four half square triangles, like we made yesterday.

Before I go any further, I'd like to mention something that is of no importance for this project, but will definitely count if you're making the Pinwheel Party Quilt.

You can make two different pinwheels with any given set of four half square triangles.
Layout 1:

Layout 2:

Now let's start:

1. Lay out your four half square triangles on your table as above.
2. Sew them together in pairs.
   
   Press the seam allowances toward the darker fabric. This way, when you sew these together, the seams will lay in opposite directions, reducing bulk.
   
3. Sew the two pairs together.  To ease the lining up of the pinwheel center, I like to sew just a little section where the seams intersect first. That way, if they're not lined up properly, I only have to rip out a couple of stitches.
   
4. Press the seam open.  This will reduce the bulk in the center of the pinwheel.
   

And there we go! A pinwheel.

Tomorrow I'l show you how I made my potholder, if you're interested.
