At the beginning of May I bought this lime green and white, all polyester shower curtain at Value Village (thrift store) for about $4.50. It was 72 X 72 inches.
We have several of these old, mildew-stained, torn, and faded outdoor pillows/cushions. I gave them a good washing in the kitchen sink, then let them thoroughly dry for a few days before recovering with the shower curtain fabric.
Meanwhile, I sewed covers for 4 of the washed pillows a week ago. I just didn't put the old pillows into the covers yet.
This afternoon I finally had time and motivation to stuff the pillows and sew them closed. I didn't bother taking the stuffing out of the old filling, but covered the old, but washed pillows with the new fabric.
Here's how the first four turned out.
I measured the remaining fabric and I have enough to make 4 additional pillow covers for a total of 8.
Cost analysis
My cost for this project was $4.50 for the shower curtain and $2.80 for a new spool of 100% white polyester thread, for a total of $7.30. (I had read that you should use all polyester thread when sewing outdoor items, as cotton breaks down over time when exposed to the elements.) I also used some Fray Check on all of the raw edges to add integrity to the seams. This was Fray Check from my sewing basket and I didn't use all that much. If I use all of my fabric to make a total of 8 pillows/cushions, they will cost less than $1 each. If I were to buy 8 all new outdoor pillows, my best guess is I would spend about $75 or $80.
I like how they turned out. By using thrifted fabric (shower curtain), and spending about 30-40 minutes on each pillow, I spared money in our outdoor living redo budget, money which is now available for some of the big ticket items.
