Seamstresses have been hiding this for years! Insert a razor blade into the needle and be amazed.

Using the cotton swab: Use it by removing the cotton from the sides, and insert a thin wire into it, which when bent will become a hook. A trick similar to the previous one, only using other items that we have at home.
Using a razor blade: Inserting a razor blade into the needle slot helps to sharpen the tip and make threading easier.
Special needles with a side slot: These needles allow the thread to be inserted sideways, which makes the process much faster.
Using beeswax lubricant: Applying a small amount of wax to the thread makes it easier to pass through the eye of the needle.
The Paper Trick: Cut a piece of paper into a V shape and place the thread in the center of the V. Then, feed the paper through the eye of the needle and the thread will slide through easily.

Using Needle Threaders: Simple tools that help thread through the eye of the needle smoothly.
Adequate Lighting: Having a direct light source over the sewing area improves visibility and makes threading easier.
Tensioning the Thread: Keeping the thread taut as it is fed through the needle prevents it from tangling or kinking.
