Disclaimer: I am NOT a seamstress by any stretch of the imagination. I can, however, sew a decent straight line, which means anything in a square or rectangle shape is fair game.
Here's the step-by-step for my cushion covers. Note I am too lazy to actually measure, so everything is eyeballed. I made 3 sets of cushion covers (plus a few other projects you'll see soon) in just a couple of hours after the baby went to bed. Since all 3 fabrics were in the same color family, I saved time (and thread!) by choosing one thread color to use for all 3 sets so I wouldn't have to rethread the sewing machine.
1. Measure out the fabric. I laid the cushion I wanted to slipcover on the folded fabric and just cut a square with a couple inches to spare on each side. Note the fabric is folded right sides together, so the unfold cut piece would look like a large rectangle. For my oversized pillow cushions, 1-1/2 yards made 2 slipcovers.
2. I hemmed the two sides that would be the opening of the pillowcase.
3. I sewed the sides shut, wrong sides out. Since I had extra fabric, I sewed with a pretty big allowance and then trimmed the extra away.
4. I checked the fit of the slipcover several times as I went along.
5. When the case was finished, I used iron-on velcro in a coordinating beige for closing it. I don't know how to do button holes or zippers, so velcro was the easiest choice for this sewing novice.
6. Voila! The couch is happy to be dressed!
