Danielle, glad you found us, it's great to have you as a member of the community, welcome to Router Forums.
I would use a pre conditioner on pine,it will raise the grain so sand before continuing.
Personally I'm not a fan of using anything on top of linseed oil.( linseed oil never hardens) why not just stain and put a hard finish on it.
Looking forward to your participation.
Filling out your profile to include (first name,tools and short bio is strictly (optional )but does help members to better relate to each other.
Thank You John
