I've already made my 4 half square triangles that I need for my pinwheel block. I have them laid out on my handy dandy portable design board (more about how to make you some of those in another post).
I flip the ones on the right over on top of the ones on the left and stitch them using my chain piece method I talked about in last weeks post on Tips, Tricks, and Tuts Tuesday.
Remember I'm not cutting them apart at each intersection yet. I take each half square triangle unit that I just sewed to the ironing board and press one set of seams up and press the other set of seams down. They're still attached with that thread in the middle from chain piecing.
By doing this, my seams will nest together like the picture below.
I then sew that seam. Sometimes I pin where the two seams intersect but most of the time I don't. After I've sewn it, that's where the TWIST comes in. First I cut the little chain thread that was holding them together.
Then I lay the block down and I grab on each side of the intersection of the seam I just sewed and I give it a TWIST.
Now take it back to the ironing board and press it. All of your seams will lay the same direction going around the block this way. And you form a cute little pinwheel in the middle when you make the TWIST.
That's it! Very easy, peasy and very FLAT!
I do this little twist thing on four patch units too, even if there isn't nearly as much bulk at the intersection. I just love the way it makes your block lay so flat. Next week on Tips, Tricks, and Tuts Tuesday I'll show you how I make 8 half square triangles from 2 squares of fabric and the magic formula to figure out what size to cut your squares.
Oh and this week I'm linking up with Lorna at Sew Fresh Quilts: Let's Bee Social. Go socialize with someone. There's lots of inspiration out there.
