Yeah, it's best to leave the eggs where they are rather than scraping them off the paper or whatever they lay on. Then they are always right side up and you don't accidentally glue them the wrong way.
If you want to keep the eggs contained (because they will lay the eggs anywhere and everywhere,) put the female on a piece of paper/cardboard/whatever and put a small cup over her so she has to lay in the confined space. She might lay a few on the edge of the cup, but the majority of them will be on the paper.
