My Buying Guides on 18X18 Throw Pillow Cases
When I first decided to refresh my living space, I realized how much difference a simple 18×18 throw pillow case could make. If you’re like me, wanting to add comfort and style without a big investment, here’s what I learned from my experience that might help you choose the perfect pillow cases.
Understanding the Size
The 18×18 inches dimension is one of the most popular sizes for throw pillows. It’s a versatile size that fits well on couches, beds, and chairs. When buying pillow cases, I always double-check that the pillow insert I have matches this size, so the cover fits snugly without being too loose or too tight.
Material Matters
I found that the material of the pillow case affects both comfort and durability. Cotton and linen are my go-to choices because they’re breathable and easy to clean. For a more luxurious feel, velvet or silk cases add a rich texture but may need more delicate care. If you have pets or kids, I recommend durable and washable fabrics like polyester blends.
Closure Types
The closure style is something I overlooked at first but now pay close attention to. Zipper closures keep the pillow insert secure and give a neat look. Envelope closures are convenient for quick changes but might let the insert peek out. Buttons can be decorative but sometimes get uncomfortable if you lean against the pillow.
Design and Color
Choosing the right design and color was the fun part for me. I matched pillow cases with my room’s color scheme and patterns. Neutral colors work well for a minimalist look, while bold prints can be statement pieces. Remember, pillow cases are an easy way to update your decor seasonally or for special occasions.
Care and Maintenance
I always check the washing instructions before buying. Some fabrics require hand washing or dry cleaning, which is less convenient for me. Machine-washable pillow cases save time and keep things fresh, especially if you use them daily.
Price and Quality Balance
While shopping, I found that higher price doesn’t always mean better quality. I look for well-reviewed brands that offer good stitching and fabric feel. Sometimes, affordable options can be just as durable and stylish.
Final Tips from My Experience
- Measure your pillow inserts before purchasing.
- Consider buying a set to mix and match designs easily.
- Think about the room’s overall style and pick pillow cases that complement it.
- Don’t be afraid to experiment with textures and colors to find what feels right for you.
I hope my insights make your search for the perfect 18×18 throw pillow cases easier and more enjoyable!
