As I mentioned yesterday, I used the same basic envelope closure pillow cover technique to recover the box cushions on our Craigslist-rehabbed porch furniture. The old covers were done the "right" way, with side panels and welting at the edges, and a zippered back. Same style as this:
Though other than the sewing technique, they looked nothing like this adorable cushion. They were dark navy with a mauve and white floral pattern and, frankly, just ugly as sin.
I haven't sewn box cushions before, and am pretty sure I could have done it the right way...but the time commitment to do so was completely overwhelming. I had ten of them to make and wanted to reuse the foam inserts, all of which were slightly different sizes, which would have meant ten different patterns, cutting out all the side panels, making all the welting...I've lost track already. So I created a little shortcut for myself, and while they are lacking a bit of that nice structured look that a true box cushion cover gives, I'm so happy with the results and even happier that it didn't take me a month to do them all. A seam runs down the middle of each side, but the frame of the furniture disguises this a bit and it's really not that noticeable at all.
As I started removing the old covers, several of the foam inserts disintegrated into dust upon contact with the air. Instead of buying new foam (which can be crazy expensive) I decided to order five euro pillows, 26"x26" ($10 each from Sears.com). These covers were done exactly as the ones for our office, just a larger size.
After making the cover for your box cushion and inserting the cushion into its cover, you get these empty corners, which don't look quite right
To disguise this, I used the easiest little trick. Pull the corner out taut with your fingers.
Then tuck it in on itself.
Play a little until it is nice and flat. Repeat on the other corners.
And that is it!
Super easy, right?!
