Some background:
I am attempting to build a desk top for my wife's home office.
I bought 5/4 s3s walnut.
I have cut the boards down to 65". Finished length will be 60"
I have not cut them to width yet but finished width will be about 5" for an overall finished glue up width of about 29-30"
Some of the boards are bowed on the face side. some on the edge side but slight enough that I should be able to remove when I cut them to final width.
While I am slightly improving with each project, I am still fairly inexperienced at wood working and even more inexperienced with hand tools.
Question is: what is the proper technique for removing the bow to have a flat face so that I can either continue hand planing to final thickness and dimensions (preferred) or run them through the small lunch box planer I have?

I currently have a LN #7 jointer, LN #62 LA Jack, and LN # 601/2 Rabbet Block plane.

Thanks to all on this fantastic site that take the time to respond.
