Specialty photography stores or arts and crafts shops, such as Michaels or Hobby Lobby, may carry photo emulsion for screen printing purposes as well. These physical stores also provide the advantage of seeing the product before purchasing and immediate availability. Additionally, some local camera shops or printing supply stores might stock photo emulsion, especially those that cater to professional photographers or screen printers. Comparing prices and product reviews online can help you find the best deal and ensure you're buying a quality product suitable for your specific needs.

Removing epoxy resin from hands can be tricky but manageable with proper care. Firstly, don’t panic and avoid using harsh chemicals or solvents as they can harm your skin. One effective method is to use a combination of vinegar (a mild acid that can help break down the epoxy) followed by soap and warm water to wash off the loosened residue. Gently rub your hands together or use a cloth. For stubborn spots, a mixture of baking soda and coconut oil can be applied; this acts as a gentle abrasive and moisturizer, respectively. Always wear gloves in the future to prevent resin contact.

A homemade wetting agent for grass can be made using mild dish soap and water. Mix about 1 to 2 tablespoons of biodegradable dish soap with 1 gallon of water. This solution helps reduce the surface tension of water, allowing it to penetrate the soil more effectively. It's a cost-effective and environmentally friendly option for addressing dry spots in your lawn, especially in compacted or hydrophobic soils. However, use it sparingly, as overuse can harm grass roots. It's ideal for periodic application during dry seasons or as needed. Always test a small area first to ensure it doesn't adversely affect your grass type.
