Hello... super newbie here. Thanks for all the great info. I've been watching Sam Alfano's video on scrollwork and trying to follow along and removing the background on a practice piece. Sorry the line work is so awful. But my problem is that in attempting the remove the background areas I end up with a bunch of furrowed lines rather than a smooth erasure of the area. I'm using a square graver. Can anyone help with tips on what I'm doing wrong? Thank you
