Frequently Asked Questions (FAQs)

1. What are the different pillow forms?

Pillow forms can have various types of fillings. Some options include polyester fill, polyester clusters, microfiber, hollow fiber, down, feather and down mix, buckwheat hulls, kapok, wool, or foam. Each filling type offers different characteristics and levels of comfort.

2. What is the rule for pillow inserts?

A general rule is to use pillow inserts that are 2 inches larger than the finished pillow cover size. For example, if you have an 18x18 pillow cover, it is recommended to use a 20x20 insert. This ensures that the pillow is fully filled and appears plump and luxurious.

3. What size pillow goes in a 20x20 cover?

For a 20x20 inch pillow cover, it is recommended to use a 22x22 inch pillow insert. This size difference allows the insert to fill out the cover fully, creating a plump and well-shaped pillow.

4. What is the coolest pillow filling?

Down is known to be less likely to trap body heat, making it a suitable choice for those who prefer a cooler sleeping experience. Down-stuffed pillows are lightweight and have a soft and cuddly feel, enhancing overall comfort.

5. What is the healthiest pillow filling?

Buckwheat hull pillow stuffing is considered a healthy and environmentally friendly alternative to conventional pillow fillings. The hulls are the outer shell of the buckwheat grain, washed and dried, and provide a natural and supportive fill for pillows.

6. What size pillow to put in 16x16 cover?

To achieve a plump pillow in a 16x16 inch cover, it is recommended to use an 18x18 inch pillow insert. The slightly larger insert fills out the cover and corners fully, creating a visually appealing and comfortable pillow.

7. How much bigger should a cushion insert be than the cover?

As a general guideline, a cushion insert should be 1-2 inches larger than the cushion cover. This allows for a plump and well-shaped cushion that is properly filled and comfortable. However, sizes can vary depending on brands and the type of filling used.

8. Will an 18x18 pillow case fit a 20x20 pillow?

For a full look, it is recommended to choose a pillow cover that is 2 to 4 inches smaller than the pillow insert. If you have an 18x18 inch pillow case, a 20x20 inch polyester pillow insert would be suitable to achieve a full look with a little give.

9. What can I use instead of pillow stuffing?

Instead of traditional pillow stuffing, you can consider using remnants of wool, fabric, or other materials to fill your project. This can be a good way to repurpose leftover materials and can work well for projects such as stuffed toys and throw pillows.
