whats the difference between spliced eye, sewn eye?

Answer 1

If the reference is to rigging, it's how an eye (integral loop) is made in the end of a rope. In a spliced eye, the end of the rope is unraveled into the individual bundles and the end is looped back to the main body of the rope. The bundles in the main rope are separated, and the separated ends are woven into the body of the rope. This leaves an eye in the end of the rope. This is the older, surer way to make an eye.

I could do a straight splice, but never mastered an eye splice.

For a sewn eye, the end of the rope is brought up along the body of the rope, and light twine is threaded on a large needle. The twine is wrapped around both the end and the body, and the needle the goes through the space between, around the end part, back through the space between, around the main part - repeat this 20 - 30 times. Quicker, easier than splicing, but not as strong.
