If those instructions are confusing you, try this: Place your accent piece right sides together with pillowcase body and sew together, sewing one side of the accent to the pillow body. Then unfold the accent piece and place the cuff fabric right sides together and sew that seam. Making a pillow case is not really hard to do but when adding an accent strip it can make it a little confusing.

"unfold" was an unfortunate choice of word for step 6, because you aren't unfolding anything (the accent strip or the cuff strip) that you folded in previous steps.

Here's how I interpret this tutorial. You have 3 pieces of fabric: the large "body" of the pillow case, a very narrow strip of accent fabric and a wider strip of fabric for the cuff.

Step 4: The accent strip of fabric is folded and pressed, wrong sides together. In this photo, the accent strip is pinned to the body of the pillowcase, raw edges together. Because the accent fabric is folded, it has 2 raw edges, so there are three "layers" of fabric on the seam line, 3 raw edges.

Step 5: The cuff strip is also folded and pressed, wrong sides together, so it also has 2 raw edges on top of each other. It is also pinned to the edge of the body of the pillowcase, on top of the accent strip, raw edges together. Now you have 5 layers of fabric in the seam line: the body of the pillowcase, the 2 raw edges of the folded accent strip and the 2 raw edges of the folded cuff.

Sew along that seam line, through all 5 layers of fabric.

Step 6: OPEN (rather than "unfold") the seam you just sewed and press it. Press the seam allowance in whichever direction you want it to go. (The author doesn't specify which direction she prefers; do whatever works for you.)

Step 7: This photo shows the finished pillowcase, turned right sides out, but it does not show step 7 itself, that is, sewing the seam around the pillowcase with the right sides together.
