How to Make an Easy No-Sew Window Seat Cushion

There’s a time in every man’s life where he needs to make an easy no-sew window seat cushion. It’s pretty much a right of passage. Everyone knows this. Don’t look at me that way!

This was my time. I’ve been training. And so because of that training my body is ready. Because I trained.

IMAG1846First and foremost, I took measurements of my window sill and promptly went to the big orange store for some 1/2″ plywood. I had my wife load it onto this metal thing with wheels so I didn’t have to get my hands dirty. I’m a fabrician now.

IMAG1845We located this terrifying machine from Fern Gully and tried to find it’s operator.

Once found we explained our dilemma- This wood is way too big! HELLLP!

I couldn’t watch what happened after that…

Once Rach unloaded this from the truck I had her give it a dry fit to see if it…fit. As it turned out, it did not fit! So I sent Rachel back to Home Depot until the job was done right. I told her this will build both character and confidence, though it may not feel that way right now.

I’m kidding. I took a little off the side with my trusty circular saw. And for the life of me…I still cannot make a straight cut. Good thing it’s getting covered! LOL!

I picked up some extra lofty quilt batting and 2″ thick foam. These are the bread and butter for our super easy no-sew window cushion sandwich. Yum!

Lay out your foam and place the plywood on top.

Use the plywood as a guide to cut the foam. First make a shallow cut about half-way through…

Then adjust your utility knife (the only utility knife that exists as far as I’m concerned) to depth…

Take your arm and push down and away to spread the foam to cut the rest of the way through. It’s really hard to tell from this angle but I’m super muscular.

Repeat the process on all of the remaining sides!

Why do fabric projects always seem so daunting? I look so dauntless while doing this. I’m literally undauntable right now.

Using a pair of scissors, cut the batting to size…

I gave myself 2+ inches on each side. You can see that the cuts kind of got away from me. Scissors: The circular saw of the fabric world.

I laid out my fabric on top and using the batting as a guide, cut the fabric to size. Once that was done, I flipped the two over.

You want to get the batting as FLAT as possible so that there are no bumps or bubbles when we attach this thing. I’m not trying to be pushy, I just want what’s best for you.

Lay your plywood on the batting/fabric sandwich and start from one side.

Pull tight, pull strong young fabric-hopper.

Here I use a 5/16″ staples which are perfect. HOWEVER! The bang bang stapler is not recommended. Use one of these. Precision is not one of bang bang’s strong suites.

Make your way down the fabric and secure with staples. If you find the fabric ripping or over-pulling, you can double fold the end to give the hardware more to hold onto.

How I see it, there are two ways to do this thing. The SUPER TIGHT rounded way (pictured in the middle), or the pretty tight rounded rectangle way (pictured left&right). I was at a crossroads here so I decided I wanted the PTRRW.

Here’s another look at the difference. Choose wisely. You PTRRW’n with me or not bro?

So I popped out a couple of staples and loosened things up a bit.

While my rapping is phenomenal. My WRAPPING is abysmal. And I really do wish I could fully articulate how I did what I did here. I’ll do my best. Only for you, though. Grab the end in one hand and pull up. Once halfway up, tuck in the excess fabric (pictured on the right). Finish pulling up the fabric and…

Secure it with a staple.

As you can see this is the the adopted corner we “love just as much” as our biologicals.

Well that escalated quickly! You can see the “rounded rectangle” method in it’s glory here. I think this took me about a half hour and it was pretty fun! It took Rachel a few hours longer but you’ll have to ask her about it yourself.

Ha! Nice job on the no-sewing, folding corners part. Even us old sewing veterans have difficulty with a nice hospital corner fold (and I used to work in a hospital!). The cushion looks very nice, loving the color, I hope Rachel likes it too. Although the dog looks somewhat worried…

Thanks that means a lot coming from a corner-folding pro! I think we were all worried at one point in the project. Rachel does like it! I have to say when I pitched the idea she was surprised I would even attempt to dabble in fabric!

Your post made me smile. I just came across your blog (search via frame mirror). And, this grabbed my attention in the post. I have 2 ikea kallax benches waiting for me to make seats. I’ve been procrastinating that project. We’re DIYers too and there is no end to projects, lol. Thanks for this lovely and detailed post. I will tackle my bench soon. Hardest part has been choosing the fabric. Ugh, I hate sewing. So this is perfect.
