My Buying Guides on 18X18 Throw Pillow Cases
When I decided to refresh my living space, throw pillows became an essential part of my decor. I found that the right pillow cases can completely transform the look of a room. In this guide, I’ll share my insights on purchasing 18X18 throw pillow cases, which I believe are a perfect size for versatility and style.
Understanding the Size
First, let’s talk about the size. An 18X18 throw pillow case fits perfectly on most standard throw pillows, making it a popular choice. I love that this size strikes a balance between being large enough to make a statement and small enough to layer with other pillows. It’s also a great option for both sofas and beds.
Material Matters
When I was on the hunt for pillow cases, the material was a huge factor. I found that different fabrics can completely change the feel of a room. Here are a few materials I considered:
- Cotton: This is a classic choice. I appreciate that cotton is breathable and easy to clean, making it perfect for everyday use.
- Linen: For a more rustic or textured look, I found linen to be fabulous. It adds a touch of elegance and feels great against the skin.
- Velvet: If I wanted to add some luxury, velvet is my go-to. It’s soft and plush, which can elevate the comfort and aesthetics of my space.
- Polyester: This synthetic option is durable and often more affordable. I found many beautiful designs in polyester that are perfect for casual use.
Design and Patterns
One of the most exciting parts of shopping for throw pillow cases is the design options. I love that I can express my personality through patterns and colors. Here’s what I kept in mind:
- Solid Colors: If I wanted a minimalist look, I would choose solid colors that complement my decor.
- Patterns: From florals to geometric designs, I found that patterns can add a fun element to my space. I often mix and match to create visual interest.
- Seasonal Themes: I enjoy changing my pillow cases with the seasons. For example, I might go for warmer tones in fall and bright colors in summer.
Closure Types
The closure of a pillow case is another detail I considered. Here are the main types I encountered:
- Zippered Closure: I prefer zippered cases as they are easy to put on and take off, making washing a breeze.
- Envelope Closure: This style is also convenient and gives a seamless look. I’ve used this type for a more casual vibe.
- Button Closure: For a decorative touch, button closures can be charming, but I found they can be a little trickier to manage.
Care Instructions
I can’t emphasize enough how important it is to check care instructions before purchasing. I tend to go for pillow cases that are machine washable, as this saves me time and effort. Some fabrics require dry cleaning, which I try to avoid for everyday use.
Price Range
Lastly, I considered my budget. The price of 18X18 throw pillow cases can vary widely depending on the material and brand. I found that it’s possible to find both affordable options and high-end designer cases. My advice is to decide how much I’m willing to spend before I start shopping, keeping in mind that sometimes, investing a little more can result in higher quality and durability.
Final Thoughts
In my experience, choosing the right 18X18 throw pillow cases can significantly enhance the overall look and feel of my space. By considering factors like size, material, design, closures, care instructions, and price, I feel equipped to make a confident purchase. I hope my guide helps you find the perfect pillow cases for your home!
