I'll throw my nickel's worth in on the eraser type: kneaded erasures are excellent for delicate work. You can tear them into little pieces, form them into shapes, gently blot with them, etc.
I'm sorry, THIS IS THE ONE I USE TOO! It's white with a blue label grip. The most bang for the swipe!
Yes, this is why I like them too. Also, when you stretch them over and over, brings the clean parts to the surface.
Hi Fig, nope not yet. I want a steady hand and clear head and with all my migraines of late, I feel like I could really mess it up right now. Thanks for asking.
I have mixed feelings. If you are going to resell it, maybe let the buyer decide what to do. I don't think you will ever be able to hide the fact that the mark was there - even erasing will leave some indication and they might just be happier dealing with it themselves. That said, if you do remove it, I agree that a kneaded eraser is the best tool. I'm a colored pencil artist and use a kneaded eraser on my work because it's the gentlest but most effective.
