If your epoxy isn't drying as expected, first ensure that you followed the mixing instructions correctly, as improper ratios can prevent curing. Also, check the temperature and humidity levels, as epoxy typically cures best at room temperature (70-80°F) with moderate humidity. If these conditions aren't met, consider moving your project to a warmer, drier location. For areas that remain tacky, applying a thin layer of fresh epoxy might help. Alternatively, using a heat gun can accelerate curing by raising the surface temperature. However, avoid direct heat which may damage the epoxy. Lastly, if these methods don't work, the epoxy might be defective, and you should consider using a new batch.

Memento ink is not oil-based; it is a water-based dye ink. Known for its quick-drying capabilities on paper, Memento ink is popular among stampers and crafters for its vibrant colors and compatibility with alcohol markers, offering a smudge-free experience when coloring stamped images. Its water-based nature means it is not waterproof, so it's not suitable for techniques requiring water over the ink unless it is heat-set or sealed. Memento ink pads are perfect for detailed stamps, producing crisp images without bleeding or fading, making them a versatile choice for various paper crafting projects.

Polypropylene fabric, known for its lightweight, durable, and resistant properties, is widely used in a variety of applications from clothing and reusable bags to medical devices. To source this versatile material, you have several options. One common way is through fabric stores, both physical and online; many of these specialize in synthetics and will offer a range of polypropylene options. Online marketplaces like Amazon and eBay are also good places to look, especially for specific types or bulk orders. If you're aiming for large quantities or specific technical qualities, contacting manufacturers directly or through B2B platforms like Alibaba could be the most cost-effective strategy. Always consider the purpose of your project when selecting the grade of polypropylene fabric to ensure it meets your needs in terms of durability, breathability, and water resistance.
