This is exactly what I was afraid of. I spent hours stripping and sanding. I hesitated staining because I was unsure how it would look. It is a blotchy, swirly mess.

This is the trim in the back hall leading to the basement. I started with this trim rather than something in the middle of living area.

I can see my standing marks, there may be some residual shellac or paint left. I am so frustrated. I will address this another time.
