The size of a duvet and a standard duvet cover can vary depending on the manufacturer and the specific product. However, in general, the duvet cover is typically slightly larger than the duvet to allow for easy insertion and removal. This extra space also helps to ensure that the duvet is fully covered and protected. Therefore, the duvet cover is usually larger than the duvet, rather than smaller. **

The choice between a duvet and a sleeping bag depends on personal preference and the specific sleeping situation. Duvets are typically more comfortable and provide a more home-like sleeping experience, while sleeping bags are more practical for outdoor activities such as camping or hiking. If you prioritize comfort and warmth, a duvet may be the better choice, but if you need something more portable and versatile, a sleeping bag may be more suitable. **

A duvet with dimensions of 200x220 cm would be the best fit for a duvet cover with dimensions of 173x224 cm. This allows for some extra room for the duvet to fill out the cover and prevent it from shifting around inside. It's important to have a duvet that is slightly larger than the cover to ensure a proper fit and a comfortable night's sleep. **

For a duvet measuring 140x200, you would need a duvet cover that is also 140x200. It's important for the duvet cover to be the same size as the duvet to ensure a proper fit and to prevent the duvet from shifting inside the cover. This will also help to keep the duvet evenly distributed and provide a comfortable sleeping experience. **

Watercolor paints are generally considered non-toxic and safe for use, as they are made from pigments mixed with a water-based solution. However, some watercolor paints may contain toxic ingredients such as heavy metals or harmful chemicals, so it is important to check the label and use them in a well-ventilated area. It is always recommended to keep watercolor paints away from children and pets, and to wash hands thoroughly after use. **

Watercolor shellac is a type of paint medium that combines watercolor with shellac, a natural resin derived from the lac beetle. This mixture creates a unique paint that has the transparency and flow of watercolors, but with the added benefit of shellac's glossy finish and durability. Watercolor shellac is often used in fine art painting and decorative arts to achieve a vibrant and long-lasting finish. **

Watercolor effects refer to the unique characteristics and techniques associated with watercolor painting. These effects include the blending of colors, transparency, and the ability to create soft, flowing lines. Watercolor effects can also involve layering colors to create depth and texture, as well as using techniques such as wet-on-wet and dry brushing to achieve different visual effects. Overall, watercolor effects allow artists to create beautiful, ethereal, and expressive artworks. **

Watercolor paints are not waterproof once they have dried. They are water-soluble, meaning they can be reactivated with water even after they have dried. This makes them a versatile medium for creating different effects and blending colors. However, if you want to make your watercolor painting waterproof, you can use a fixative spray or apply a watercolor varnish once the painting is completely dry. **
