Sharing is caring!

Learn how to crochet a textured crochet envelope pillow cover. This easy crochet pillow case pattern is removable so you can wash it.

The Piazza Crochet Pillow pattern is designed to overlap so that you can pull it open and remove the pillow. This allows you to wash that crochet pillow cover. Which means you can actually use it around the house.

Customize your crochet pillow even more by adding buttons, fringe or tassels. I considered adding buttons to the envelope closure side to make both sides decorative. The possibilities are endless!

The Inspiration For This Pillow

Adding a throw pillow to your dining room chair is a tough decision. Well, it was for me. I really needed a pillow because I’m short and our chairs are so deep.

However, I’m also a mom, of four elementary age kids. So our dining room feels more like a school lunch table most of the time. Needless to say, I was a bit worried about the mess.

Especially if said mess ended up on my handmade crochet pillow. I didn’t really have to consider this problem when I designed the Lombardy Crochet Pillow. It was designed for my office chair, so no kids, no food and I could just seam it up.

But adding a crochet throw pillow to my dining chair is another matter. I decided on a removable crochet pillow cover. So I can simply wash it, as often as needed.

For the Piazza Crochet Pillow I chose a 20″ x 20″ cushion to cover. Included with this pattern are other common square pillow sizes. Plus a chart for lengths, so you can crochet a rectangle pillow if you want. Just refer to the charts for your widths and lengths.

The chart includes pillow cover lengths by size for the envelope closure. You can easily adjust this, as you only need to add or subtract rows.

I love crocheting with Bernat Maker Home Dec yarn for crochet throw pillows and home decor. The unique construction of the yarn makes it durable and anti-pilling. These are essential for throw pillows that you actually plan to use.

The Lombardy Crochet Pillow Pattern turned out so amazing with this yarn. I used one ball of Bernat Maker Home Dec yarn in Pebble Beach for a 12″ x 18″ lumbar pillow. The lemon peel stitch crocheted up great for the variegated yarn.

Can I substitute yarns?

Absolutely. You want to choose a yarn that will hold up to use, especially if you plan to use it on your couch or dining chair. Lion Brand makes a yarn called Sponge Cake that is similar in construction and also a #5 bulky yarn.

I love these round baskets Rebecca from Yarn + Chai designed with Bernat Maker Home Dec yarn. This yarn makes fantastic useful projects for home.

For this crochet pillow pattern I used two stitches in a simple two row repeat. The half double crochets are worked into the blo-or back loop only. Normally you crochet under both loops, so this adds to the texture.

The other stitch is the extended half double crochet. This one is crocheted by making a chain 1 extension before the regular hdc. I have a post explaining exactly how to crochet extended half double crochet stitch if you’d like a detailed tutorial.

The texture created with these two stitches is perfect for an otherwise simple pillow design. I love the easy ribbed effect of these half double crochet stitches together.

The Construction For This Crochet Envelope Pillow

This crochet pillow case is worked flat, in one long rectangle. The pillow cover is designed to overlap the pillow in an envelope fold. This makes the pillow removable and the crochet pillowcase washable.
