Today I have for you the partial seam edition...
There is a partial seam in section one, and if you haven't done a partial seam before that might sound daunting. But trust me, there is no tricky technical sewing here, just a particular order in which to sew your seams that might not be immediately apparent.
I took lots of photos as a sewed this part together so you can follow along if you need to.
I am only working on part of section 1 here (5 strips in from the left inclusive). I began by laying out the pieces using the pattern diagram as a guide.
Then I stitched the pieces together that I could see went together logically enough. Now you are ready to sew your partial seam joining the long and short strips together to where I have my finger. You are going to sew this seam down from the top about 1.5" (not all the way to the bottom, hence the 'partial seam').
I pinned the strips where I wanted to stop.
When you turn it the right way up, it looks like this and you are ready to sew it to the square in square block above.
Next, attach that pair of 8.5" strips that go on the right hand side of the block. Are you getting a sense of the logic? Fun, right? Attach that pinwheel to the bottom of those four strips now.
Now, flip the whole thing over. You're going to finish that seam that is open on the left.
That yellow pin at the top is where my previous unfinished seam ended. Start from there and sew to the bottom. This is your last seam in this part of the block.
Give it a good press and admire your handiwork!
